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. Improvements are also provided for performing channel state information estimation including the use of optimum filter lengths based on channel selectivity and adaptive decision-directed channel estimation. These improvements enhance the performance of various communication systems and consumer electronics. Particular improvements are also provided for decoding HD Radio signals, including enhanced decoding of reference subcarriers based on soft-diversity combining, joint enhanced channel state information estimation, as well as iterative soft-input soft-output and list decoding of convolutional codes and Reed-Solomon codes. These and other improvements enhance the decoding of different logical channels in HD Radio systems.

摘要： A method and apparatus for processing transmissions in a wireless communication system to detect whether a transmission unit contains transmitted data. The method comprises: receiving a plurality of samples of a transmission unit; determining an average signal-to-disturbance ratio of the plurality of samples; determining for each sample at least one bit reliability indicator, which is related to the probability that the transmitted bit is a one or a zero; generating an averaged function of the bit reliability indicators from the plurality of received samples; and applying a test to compare an average of In cosh(.), with a factor proportional to the average signal-to-disturbance ratio to determine if the transmission unit contains transmitted data.

摘要： Method and decoding device for decoding a convolutionally coded input data signal y. The input data signal is multiplied with a scaling factor Lc (8) and then demultiplexed (6). The demultiplexed input data signal LcS is then turbo decoded (5) in order to obtain decoder output likelihood ratio data Λ. The scaling factor Lc is updated (7) for a next iteration in dependence on a combination of a posteriori likelihood data based on turbo decoded output data Λ and a priori likelihood data based on the demultiplexed signal LcS.

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来改善用户设备（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）。多个协作的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： Embodiments are provided for transmitting channel information, such as control channel information, using lower resources at the transmitter combined with using apriori information associated with channel information in the decoder of the receiver. The apriori information represent predictable information that can be predicted by the receiver and is not transmitted with the channel information by the transmitter. The transmitter determines the apriori information for the channel and codes the channel information into bits and fields excluding the apriori information. Upon receiving the channel information, the receiver determines the apriori information associated in accordance with previously received information. The apriori information is then provided as probability information for input to the decoder. The decoder then decodes the received information in accordance with the apriori information.

摘要： Systems, methods, and an article of manufacture for performing serial concatenated decoding are shown and described. The decoding includes monitoring a measure of the number of corrections made to a plurality data blocks during outer decoding and determining whether applying sub-optimal inner decoding would reduce a computational load experienced by a processor performing the serial concatenated decoding when compared to the computation load experienced by the processor when optimal inner decoding is applied.

摘要： A multi-tiered CSI vector quantizer (VQ) is provided for time-correlated channels. The VQ operates by quantizing channel state information by reference to both the current channel state information and a prior channel state quantization. A system is also provided that uses multi-tiered CSI quantizers. Enhanced signaling between the transmitter and receivers is provided in order to facilitate the use of multi-tiered CSI quantizers.
