摘要
Abstract
Joint Detection is one of the most strenuous tasks of the TD-SCDMA system. There have been a lot of efforts made on it, of which the most efficient one is the algorithm using Block-FFT.However ,Block-FFT can only be used with approximating the system matrix as block circulant.Two new techniques are proposed to modify the system matrix to be circulant .The system equation is strictly equivalent after modification with these two techniques .Because of the strictly equivalent characteristics ,Inter-Symbol Interference (ISI) can be thoroughly eliminated after equalization ,which proves remarkable performance improvement comparing with the approximating method.关键词
