摘要： Bit interleaving method for interleaving a QC-LDPC codeword made up of N cyclic blocks each consisting of Q cyclic block bits and the constellation word being made up of M bits with N being not a multiple of M. The bit interleaving comprises a cyclic block permutation step, a bit permutation step and a dividing step, where a first rule is applied to the N-N' cyclic blocks, with N' = N -X and X = rem(N, M) and a second rule is applied to the X cyclic blocks. After the cyclic block permutation process and according to the first rule, the N' cyclic blocks are divided so that the Q bits in each of the N' cyclic block are each allocated to a bit of an identical bit index in Q constellation words and the Q constellation words are each made up of one bit from each of M different cyclic blocks, said M different cyclic blocks being common to said Q constellation words.

摘要： A signal processing system and method, and an apparatus are provided. A phase recovery apparatus may be used to: receive a feedback signal fed back by an information iteration apparatus, perform, based on the feedback signal, phase recovery on a signal output by an equalizer, and output a phase-recovered signal to a post filtering apparatus, so that the post filtering apparatus performs noise filtering on the phase-recovered signal, and outputs a noise-filtered signal to the information iteration apparatus. To be specific, the phase recovery may be performed, based on the signal fed back by the information iteration apparatus, on the signal output by the equalizer. Because output of the information iteration apparatus is more accurate in determining the signal, precision of the phase recovery can be improved, cycle skipping is reduced, and input signal quality of the post filtering apparatus is improved. Therefore, a problem that performance improvement of an entire system is limited because an existing turbo iteration manner cannot improve or cannot greatly improve input signal quality of a post filter can be resolved, and system performance is improved.

摘要： An adaptive coding scheme for nonlinear channels improves reliability and an efficiency in digital communication networks. The method monitors channel statistics to analyze an extrinsic information transfer chart of the channels. The channel statistics are fed back to the transmitter to adapt forward error correction coding. A parametric analysis method uses a Gaussian mixture model. The statistical information feedback can adapt an ARQ sheme by adding a weighted received signal to the original coded signals to reduce nonlinear distortion. Trellis shaping can make the transmitting signal preferable for nonlinear channels.

摘要： A method for performing constellation superposition by an evolved Node B (eNB) is described. The method includes determining an admissible data constellation for a second user equipment (UE) based on a data constellation of a first UE. The first UE and the second UE share the same time-frequency resources. The method also includes sending an indication that superposition coded modulation is being employed by the first UE and the second UE. The method further includes sending modulation and coding schemes (MCSs) and/or transmission power percentages used by each of the first UE and the second UE to the other UE.
