Method for generating a key pair and transmitting a public key or request file of a certificate in security
A method for generating a key pair and transmitting a public key or request file of a certificate in security is provided. Usually, when a user applies for a certificate, a public-private key pair is always generated by a client side; the public key is combined with the user information to form the certificate; the CA's signature enables validity of user's certificate. However, in other cases, the client side is not a perfectly secure environment, so the private key of the user generated from the client side may be filched by a hacker, or may be replaced by a forged public key. On this occasion, the hacker can disguise the user without being detected. The method of the present invention is to use an information security device to generate a public-private key pair, the private key is saved within the information security device; the public key can be exported; and the information security device can generate authentication information for verifying the public key. The CA can determine whether the public key is generated by the information security device or not by verifying the authentication information. By the method provided by the present invention, the security of online transactions can be ensured effectively. |

Association information is used to build association trees to associate base pages and embedded objects at a proxy. An association tree has a root node containing a URL for a base page, and zero or more leaf nodes each containing a URL for an embedded object. In most cases, an association tree will maintain the invariant that all leaves contain distinct URLs. However, it is also possible to have an association tree in which the same URL appears in multiple nodes. An association tree may optionally contain one or more internal nodes, each of which contains a URL that is an embedded object for some other base page, but which may also be fetched as a base page itself. Given a number of association trees and a base-page URL, a prefetch system finds the root or interior node corresponding to that URL (if any) and traverses the tree from that node, prefetching URLs until the URL of the last leaf node is prefetched. The prefetching starts the process of bringing over the various embedded objects before the user or program would ordinarily fetch them. |

Systems and methods for distributed node detection and management
A discovery agent is running on a node within the network group. The network group is shielded from an administrative system by a communication limiting device. The communication limiting device prevents the administrative system from detecting nodes within the network group. The communication limiting device, however, does not prevent the node running the discovery agent from identifying other nodes within the network group. The discovery agent detects one or more nodes within the network group and transmits data identifying these nodes to the administrative system. Accordingly, the administrative system may identify and manage the newly detected nodes using a management agent installed on the nodes. |

Transmission behaviour for support of cell measurements
The present invention relates to a cellular communication and addresses the problem of an LTE UE measuring downlink quality when the load in cell varies instantaneously and over a wide frequency spectrum. The UE lacks capacity to measure over frequency bandwidth and time needed to make a cell load measure with sufficient reliability for making a inter-cell handover or an inter RAT handover.

The power may be controlled for specific time slots in the narrow frequency band for the terminal to measure on. This is advantageous because then the waste power needed for enabling the UE measured can be reduced and the extra interference caused by the invention be reduced. |

Estimating bit error probability (BEP) in an edge wireless system
Distribution parameter mapping determines the bit error probability (BEP) of a burst transmitted from a base station to the mobile station using a modulation and coding scheme (MCS) specified in the EDGE standard. Depending on whether the multi-bit soft decisions of the burst most resemble a Gaussian or a Rician distribution, the statistical parameters μ and σ or A and u are determined. The ratio μ/σ or A/σ is mapped to an empirically determined BEP in a Gaussian or Rician lookup table, respectively. The BEPs are not influenced by the degree of code redundancy in the MCS. The BEPs for the four bursts in a radio block are then averaged, filtered and quantized according to the EDGE standard. The quantization level of the average BEP is reported to the base station so that subsequent radio blocks can be transmitted using an MCS that is appropriate for the estimated BEP. |

Hard iterative decoder for multilevel codes
Two decoding algorithms are introduced for the decoding of multi-level coded modulation and other types of coded modulation involving component codes and interleaving operations. An improved hard iterative decoding (IHID) algorithm is presented that improves upon a hard iteration decoding technique by adding a stopping criterion. Also, a list Viterbi hard iteration decoding (LV-IHID) algorithm is presented that employs list decoding in conjunction with the IHID algorithm. Both of these decoding algorithms improve upon conventional multi-stage decoding by reducing the effective error multiplicity that is observed at the lowest coding level. It is demonstrated that the LV-IHID algorithm performs close to soft iterative decoding. The computational and delay complexity of the proposed decoding algorithms compare favorably with soft iterative decoding strategies. Also, a novel labeling strategy for MLC design is presented. |

Automatic frequency offset compensation in zero-intermediate frequency receivers using minimum-shift keying (MSK) signaling
Carrier frequency offset (CFO) between a transmitter and receiver signaling at 2 Mbps data rate with a 11110000 pattern as the preamble period is corrected within one preamble time period using free-running coarse and fine carrier frequency offset estimations. Two estimates for the CFO are computed, coarse and fine. The fine one is computationally accurate but may not be correct because of a potential wrap at ±180° in the computation. The coarse one is not accurate but delivers the approximate CFO value without wrap over. The comparison between the coarse and fine estimates thus may be used to detect a wrap over in the fine estimate and modify the fine estimate accordingly. Thereafter the compensated fine CFO estimation is used for carrier frequency offset (CFO) compensation. |

Methods, apparatus, and systems for coding with constrained interleaving
Serially-concatenated codes are formed in accordance with the present invention using a constrained interleaver. The constrained interleaver cause the minimum distance of the serial concatenated code to increase above the minimum distance of the inner code alone by adding a constraint that forces some or all of the distance of the outer code onto the serially-concatenated code. This allows the serially-concatenated code to be jointly optimized in terms of both minimum distance and error coefficient to provide significant performance advantages. Constrained interleaving can be summarized in that it: 1) uses an outer code that is a block code or a non-recursive convolutional code, and as such, there are multiple codewords present in the constrained interleaver, 2) selects a desired MHD, 3) selects an interleaver size and a set of predefined interleaver constraints to prevent undesired (low-distance) error events so as to achieve the desired MHD, and 4) performs uniform interleaving among the allowable (non-constrained) positions, to thereby maximize or otherwise improve the interleaver gain subject to the constraints imposed to maintain the desired MHD. |
