摘要： User equipment (UE) cooperation can be improved by relaying partial soft information to target UEs. More specifically, a cooperating UE may relay a subset of log-likelihood ratios (LLRs) to the target UE. The subset of LLRs may correspond to fewer than all resource blocks of the original transmission. This may allow UE cooperation to be effective when the cooperating UE was only able to decode a portion of the original transmission. This may also allow fewer network resources (e. g., bandwidth, etc. ) to be used when the target UE does not need all of the soft information to decode the original transmission. Multiple cooperating UEs can provide different subsets of LLRs, and the subsets may or may not overlap with one another.
摘要翻译：可以通过将部分软信息中继到目标UE来提高用户设备（UE）协作。更具体地，协作UE可以将对数似然比（LLR）的子集中继到目标UE。 LLR的子集可以对应于比原始传输的所有资源块少。这可以允许UE协作在协作的UE仅能够对原始传输的一部分进行解码时有效。当目标UE不需要所有软信息来解码原始传输时，这也可以允许使用更少的网络资源（例如，带宽等）。多个合作的UE可以提供不同的LLR子集，并且子集可以或可以不彼此重叠。

摘要： Systems and methods for decoding block and concatenated codes are provided. These include advanced iterative decoding techniques based on belief propagation algorithms, with particular advantages when applied to codes having higher density parity check matrices. During iterations of the belief propagation, variable-to-check messages may be calculated. According to some embodiments, a scaling factor may be calculated based on the smallest absolute values in a set of variable-to-check messages, and may be used to scale the messages passed during the belief propagation. According to other embodiments, the positive or negative signs of the variable-to-check messages may be compared and used to generate a modified variable-to-check message. According to other embodiments, sparse parity check matrices may be generated and used to produce updated log-likelihood ratios with soft-input soft-output message passing. These and other improvements enhance the decoding of H/M/LDPC codes, including Reed-Solomon codes which may be used in HD Radio systems.

摘要： A technique for estimating channel data probability in a multi-user or multiple- input multiple-output communication system is disclosed. The technique uses parallel Markov Chain Monte Carlo simulation to select a plurality of hypothetical channel data patterns. Channel data bit probabilities are obtained by summing conditional bit probabilities, where the conditional bit probabilities are conditioned on an observation of the multi-channel signal and the hypothetical channel data patterns.
