| The present invention relates to a data processing apparatus and a data processing method which can improve the tolerance to errors of code bits of an LDPC code such as burst errors or erasure. Where one symbol is formed from two or more code bits of an LDPC (Low Density Parity Check) code, a column twist interleaver 24 carries out a re-arrangement process of re-arranging the code bits of the LDPC code such that a plurality of code bits corresponding to the value 1 included in one arbitrary row of a parity check matrix are not mapped to one symbol. The present invention can be applied, for example, to a transmission apparatus which transmits an LDPC code. | ||||||

| A communications system can provide methods of dynamically interleaving streams, including methods for dynamically introducing greater amounts of interleaving as a stream is transmitted independently of any source block structure to spread out losses or errors in the channel over a much larger period of time within the original stream than if interleaving were not introduced, provide superior protection against packet loss or packet corruption when used with FEC coding, provide superior protection against network jitter, and allow content zapping time and the content transition time to be reduced to a minimum and minimal content transition times. Streams may be partitioned into sub-streams, delivering the sub-streams to receivers along different paths through a network and receiving concurrently different sub-streams at a receiver sent from potentially different servers. When used in conjunction with FEC encoding, the methods include delivering portions of an encoding of each source block from potentially different servers. | ||||||

| For writing data to multi-track tape, a received data set is received and segmented into unencoded subdata sets, each comprising an array having K2 rows and K1 columns. For each unencoded subdata set, N1-K1 C1-parity bytes are generated for each row and N2-K2 C2-parity bytes are generated for each column. The C1 and C2 parity bytes are appended to the ends of the row and column, respectively, to form encoded C1 and C2 codewords, respectively. All of the C1 codewords per data set are endowed with a specific codeword header to form a plurality of partial codeword objects (PCOs). Each PCO is mapped onto a logical data track according to information within the header. On each logical data track, adjacent PCOs are merged to form COs which are modulation encoded and mapped into synchronized COs. Then T synchronized COs are written simultaneously to the data tape where T is the number of concurrent active tracks on the data tape. | ||||||

| A reception device includes reception antennas and an address generation unit that converts a write-in or read-out order of channel estimation values according to a rearrangement rule. A storage unit writes in or reads out channel estimation values in the converted order, and an address generation unit converts a data sequence write-in or read-out order according to the rearrangement rule. A signal storage unit writes in or reads out data sequences in the converted order, and a replica generation unit generates a replica signal by re-modulating the data sequence according to the channel estimation value. A cancel unit successively generates a stream signal in which a data sequence interference signal is cancelled, by using the channel estimation value, the data sequence, and the replica signal. | ||||||

| 移動局が複数の通信方式に適応する場合でも、移動局の回路規模の増大を最小限に抑えつつ、各通信方式で同等のダイバーシチ効果を得ることができる移動局。SC−FDMA通信またはOFDMA通信のいずれかを行う移動局(100)であって、インタリーブ部(103)は、SC−FDMA通信およびOFDMA通信のいずれが行われる場合にも、複数のコードブロックに分割される複数のリソースエレメントを複数のコードブロック間においてインタリーブする。また、OFDMA通信が行われる場合にのみ、S/P変換部(107)は、データシンボルを並列に変換してOFDMシンボルを生成する。シフト部(108)は、S/P変換部(107)から入力されるOFDMシンボルに対して、OFDMシンボル毎に異なる周波数シフトを与えることで、インタリーブ後の複数のコードブロック毎の複数のリソースエレメントを周波数領域に分散配置する。 | ||||||

| <P>PROBLEM TO BE SOLVED: To provide a system and method for modulation diversity. <P>SOLUTION: The system and method for modulation diversity uses interleaving. Code bits are placed into groups and are then shuffled within each group. An interleaver uses a bit-interleaver solely to achieve m-ary modulation diversity and uses a two-dimension interleaved interlace table and a run-time slot-to-interlace mapping to achieve frequency diversity which provides better interleaving performance without the need for explicit symbol interleaving. <P>COPYRIGHT: (C)2011,JPO&INPIT | ||||||
