Lattice reduction-aided equalization techniques have emerged as a low-complexity method to achieve the same diversity as maximum likelihood detectors. We address the VLSI implementation of these LR-aided equalizers by modifying the CLLL algorithm from a fixed-point hardware perspective. We then apply the modified algorithm together with additional micro-architecture and operation scheduling enhancements...
Orthogonal space-time block codes (OSTBC) are attractive in that they can achieve full diversity and linear complexity of maximum likelihood (ML) decoding. However, the OSTBC have a low symbol rate due to the limitation of the orthogonality of the code structure. Most of the high-rate STBC achieve full diversity based on ML decoding at the receiver that is computationally expensive. In order to achieve...
