Jammer detection based adaptive PLL bandwidth adjustment in FM receiver
A frequency synthesizer within an FM receiver employs a Phase-Locked Loop (PLL) to generate a Local Oscillator (LO) signal. The LO signal is supplied to a mixer. The FM receiver also includes jammer detection functionality. If no jammer is detected, then the loop bandwidth of the PLL is set to have a relatively high value, thereby favoring suppression of in-band residual FM. If a jammer is detected, then the loop bandwidth of the PLL is set to have a relatively low value, thereby favoring suppression of out-of-band SSB phase noise. By adaptively changing loop bandwidth depending on whether a jammer is detected, performance requirements on sub-circuits within the PLL can be relaxed while still satisfying in-band residual FM and out-of-band SSB phase noise requirements. By allowing the VCO of the PLL to generate more phase noise due to the adaptive changing of loop bandwidth, VCO power consumption can be reduced. |

Method for suppressing acoustic feedback in a hearing device and corresponding hearing device
A hearing device (HD) incorporates a method for adaptive cancellation of acoustic feedback (AF). The method comprises generating an estimated feedback signal (EF) and subtracting the estimated feedback signal (EF) from the microphone signal (MS) before feeding it to a signal processor (SP) providing the primary hearing device function. The estimated feedback signal (EF) is generated in an adaptive filter (FE1), which is controlled using a least-mean-square algorithm, which operates on an error signal (E) and a reference signal (R). The algorithm may behave erroneously if the feedback path changes while a signal with low HF content, such as speech, is received. In this case, the hearing device (HD) will not be able to quickly adapt the HF characteristic of the adaptive filter (FE1) to the changed conditions. The adaptive filter (FE1) may thus have an incorrect HF gain when a subsequent signal with high HF content is received. This may lead to whistling or, alternatively, to an unwanted suppression of the subsequent signal. The problem is solved by modifying a filter function (H) applied to the error signal (E) and to the reference signal (R) in dependence on estimated relative amounts of high- and low-frequency signal content in the microphone signal (MS). |

Adaptive loudness levelling for digital audio signals
A time-domain method of adaptively levelling the loudness of a digital audio signal is proposed. It selects a proper frequency weighting curve to relate the volume level to the human auditory system. The audio signal is segmented into frames of a suitable duration for content analysis. Each frame is classified to one of several predefined states and events of perceptual interest is detected. Four quantities are updated each frame according to the classified state and detected event to keep track of the signal. One quantity measures the long-term loudness and is the main criterion for state classification of a frame. The second quantity is the short-term loudness that is mainly used for deriving the target gain. The third quantity measures the low-level loudness when the signal is deemed to not contain important content, giving a reasonable estimate of noise floor. A fourth quantity measures the peak loudness level that is used to simulate the temporal masking effect. The target gain to maintain the audio signal to the desired loudness level is calculated by a volume leveller, regulated by a gain controller that simulates the temporal masking effect to get rid of unnecessary gain fluctuations, ensuring a pleasant sound. |

Multicast signals are transmitted from a source to user terminals via multicast paths through a set of nodes in a network. A first node, such as a ‘last-hop’ router, may send toward the source corresponding join and prune messages, the join message to establish a new multicast path from the source to a user terminal, and the prune message to discontinue the old multicast path from the source to the user terminal. The router sends the join message and the prune message over the new multicast path and the old multicast path. A second node located at the bifurcation of the new multicast path and the old multicast path detects the reception of both the join message and the prune message and steers, either directly or via delegated downstream nodes, the switch from the old multicast path over to the new multicast path without loss or undue duplication of packets sent from the source to the user terminal. |

Access control for an IP access network to multicast traffic
A method and arrangement are proposed for controlling access by a client node to multicast traffic via an access network. When a client node sends a message to an access node of the access network requesting access to a multicast channel, the access node modifies this request by adding identification information to the message for identifying the client node before forwarding it to a router capable of routing multicast traffic streams. The router uses the identification information to consult access data stored for the client node and returns an acknowledgement message to the access node, indicating whether access is permitted. If access is granted, the access node streams the multicast channel to the client node. Modifying the multicast request message using the access node to include identification information allows the access control to be performed in a more centralized manner while retaining the security of a port-based access control. |

Handover control
The signal strength available to a mobile unit is periodically monitored (21), and if it falls below a threshold value X(off) the handset (40) determines whether the signal strength on an alternative network is greater than a value Y(on). If such a connection is available, a handover attempt is initiated (3). If the handover attempt (3) fails (step 4), the relevant threshold value X(off) and Y(on), depending on the cause of failure, is then raised (40) so that future handoffs are not attempted in those same conditions. If the call fails in these circumstances, the caller will have to establish a new call (step 1). If the handover is successful, (step 5) then one or both of the handover thresholds (X(off), Y(on)) may be lowered (step 51), allowing future handovers to take place more promptly. Lowering may be done in smaller increments than increases, or less frequently. By varying the threshold values empirically more efficient handover can be achieved than by pre-setting a permanent value. |
