摘　　要：针对多用户UWB信道存在的符号间干扰和用户间干扰问题,提出了一种用于DS-UWB/TH-UWB接收机的较少复杂度的自适应均衡技术及相应算法,并与传统算法在复杂性和性能方面进行了比较。研究结果表明所提出的算法在运算量上远小于单独使用RLS算法,在输出误差的收敛上远快于单独使用LMS算法。A new adaptive equalization technology aiming at the intersymbol and interuser interferences in the multiuser UWB channels was presented specially for DS-UWB/TH-UWB receivers. Its computational complexity and convergence rate were compared with the traditional algorithms. The research results show that the computational complexity of this technology is less than employing RLS method solely and the convergence rate of this technology is farther off employing LMS method solely.
