Available spectrum resources are becoming scarcer, while additional services are being integrated into wireless devices. Cognitive radio and multiple-antenna (MIMO) techniques can be combined to provide a solution to this dilemma. Given the currently available frequency bands and a set of bit-rate constrained services to be transmitted, the antennas can be partitioned among frequency bands and the...
In this paper, we present a novel CRC-aided turbo equalization approach that exploits the cyclic redundancy check (CRC) to reduce computational complexity. The essential idea is that, during the iterative process, once a data block in the data frame is detected totally correct by CRC, we can set all the log likelihood ratio (LLR) of the bits in this block a fixed high value for the next iteration,...
