摘要： Techniques for sending signaling information using hierarchical coding are described. With hierarchical coding, individual messages for users are encoded using multiple interconnected encoders such that (1) the message for each user is sent at a data rate suitable for that user and (2) a single multicast message is generated for the messages for all users. A base station determines data rates supported by the users and the code rates to achieve these data rates. Each data rate is determined by one or more code rates. Signaling information for the users is mapped to data blocks to be sent at different data rates. Each data block is then encoded in accordance with the code rate(s) associated with the data rate for that data block. A final coded block is generated for all users and transmitted. Each user performs the complementary decoding to recover the message sent to that user.

摘要： A method for parallel concatenated (Turbo) encoding and decoding. Turbo encoders receive a sequence of input data tuples and encode them. The input sequence may correspond to a sequence of an original data source, or to an already coded data sequence such as provided by a Reed-Solomon encoder. A turbo encoder generally comprises two or more encoders separated by one or more interleavers. The input data tuples may be interleaved using a modulo scheme in which the interleaving is according to some method (such as block or random interleaving) with the added stipulation that the input tuples may be interleaved only to interleaved positions having the same modulo-N (where N is an integer) as they have in the input data sequence. If all the input tuples are encoded by all encoders then output tuples can be chosen sequentially from the encoders and no tuples will be missed. If the input tuples comprise multiple bits, the bits may be interleaved independently to interleaved positions having the same modulo-N and the same bit position. This may improve the robustness of the code. A first encoder may have no interleaver or all encoders may have interleavers, whether the input tuple bits are interleaved independently or not. Modulo type interleaving also allows decoding in parallel.

摘要： A method and a device (20) for decoding a frame capable of being split into p sub-frames each consisting of k information symbols, a first n−k redundant symbols and a last n−k redundant symbols. The decoding process uses two individual decoders (21, 23) which concurrently produce extrinsic data (Extr1i, Extr2i) respectively concerning information symbols and interleaved information symbols. The values of the extrinsic data (Extr1i, Extr2i) are refined by cross-feedback of said data to the input of the decoders (21, 23).

摘要： Reduced complexity ARP (almost regular permutation) interleaves providing flexible granularity and parallelism adaptable to any possible turbo code block size. A novel means is presented by which any desired turbo code block size can be employed when only requiring, in only some instances, a very small number of dummy bits. This approach also is directly adaptable to parallel turbo decoding, in which any desired degree of parallelism can be employed. Alternatively, as few as one turbo decoder can be employed in a fully non-parallel implementation as well. Also, this approach allows for storage of a reduced number of parameters to accommodate a wide variety of interleaves.

摘要： Iterative decoder comprising a plurality of servers which perform the iterative decoding of a data block each, an input buffer memory and a control unit which performs a statistical multiplexing of the data at input, which are firstly stored in the input buffer memory and successively processed by one of the servers. The input buffer memory comprises N+L memory locations, where N is the number of servers and L is the number of so-called additional locations. Each block to be decoded which is received while all the servers are busy is stored in one of the L additional locations possibly available, or it is lost if the input buffer memory is entirely filled. The number L of additional locations and the number N of servers are such that the probability PB of a block being lost, calculated on the basis of a queuing model of D/G/N/N+L type, satisfies the condition PB≦α·FER*, where FER* is the error rate in the blocks allowed and α
