    摘要: Real-time selection of interference cancellation schemes based on transmission parameters and amount of resource overlap between the desired payload and the interfering payload. Codeword level interference cancellation may be performed where the signal quality of the interfering signal indicates that the interfering payload will be decoded correctly. When performed, codeword level interference cancellation may be monitored to determine if decoding the interfering payload is converging. Other interference cancellation schemes may be selected based on the signal quality of the interfering signal or non-converging decode of the interfering payload. The number of iterations for iterative decoding in codeword level interference cancellation may be dynamically selected. The decoder output (e.g., soft bits) may be used to perform interference cancellations before the decoder is fully converged. Iterative decoding may be performed in multiple passes and soft decision output form one pass may be used to initialize the decoder for a subsequent pass.

    摘要: A system, method and device for error detection/estimation in OFDM communications systems is proposed. The disclosed mechanism allows an efficient error prediction in a received data block (e.g. a packet) without using error detection codes that may impair spectral efficiency (due to the overhead) especially when very small size packets are used. In order to do that, it generates a decision variable with the aim to check whether a received block has errors or not, without resorting to the use of error-detection codes.

    摘要: The present invention provides a decoding method, a decoding apparatus, and a communications system, which implement multi-level coding in a manner combining soft-decision error correction coding and hard-decision error correction coding, implement multi-level decoding in a manner combining soft-decision error correction decoding and hard-decision error correction decoding, so as to integrate advantages of the two manners: compared with a manner in which soft-decision error correction coding and decoding are performed on multiple levels, a manner in which soft-decision error correction coding and decoding are performed on only one level reduces system complexity and resource overhead; and performing hard-decision error correction coding and decoding on other levels on a basis of performing soft-decision error correction coding and decoding on one level ensures gain performance, thereby meeting a gain requirement of a high-speed optical transmission system.
