排序QR分解MIMO检测器在FPGA中的实现
Implementation of FPGA based sorted QR decomposition detector for MIMO
摘要
Abstract
Detection is a dominating part for MEMO systems not only for its importance in function but also for its complexity in whole systems.Based on analysis of presented algorithms,a new Sorted QR Decomposition(SQRD) based on Givens rotation is carried out.The complex matrix is first extended into a block-wise symmetric real number counterpart, and then the complexity of QR decomposition in real number domain is reduced dramatically.The process of hardware implementation is illustrated step by step, and then the simulation results show that SQRD algorithm satisfies the demand of realistic MIMO systems in terms of both performance and resources of FPGA,which guarantee the development of the MIMO prototype.关键词
