摘要： Methods and systems are provided for searching for a codeword from a plurality of codewords in a codebook for use in precoding, for example, as used in a multiple-input multiple-output (MIMO) transmission system. Tree search and recursive algorithm techniques may be utilized to reduce the complexity and enhance the efficiency of the codebook search. Distance values may be determined between an optimal codeword and codewords in a codebook. The distance values may be accumulated for a group of the k-best codewords. Additionally or alternatively, a codeword from the codebook may be removed from consideration if the codeword meets a stop rule condition. A codeword may be selected from the codebook based on a minimum distance value from the optimal codeword.

摘要： Techniques are provided for transmitting and receiving a mother code in an incremental redundancy hybrid automatic repeat-request protocol. A set of information bits corresponding to a message may be encoded and interleaved to produce the mother code. Each bit position of the mother code may be mapped to an output symbol, and each output symbol may be mapped to an antenna for transmission. One or more transmissions of symbols contained in the output symbols may be performed, where each transmission may include puncturing the mother code by selecting one or more symbols from the of output symbols, and transmitting each symbol in the one or more symbols on an antenna corresponding to that symbol. The mother code may be decoded, in part, by determining combinable bits contained within a set of received symbols, and computing one or more log-likelihood ratio values corresponding to each symbol in the set of received symbols.
