摘要： 针对稀疏信道的码片均衡,提出了一种RLS的改进新算法-SM RLS算法.理论分析与计算机模拟结果表明SMRLS码片均衡器性能优于传统的Rake,在稀疏信道下与经典的M RLS码片均衡器相比稳态误差基本保持不变,收敛速率提高且大大减少了运算量.

Abstract: High-speed packet transmission is an important characteristic in the 3rd generation mobile communication system.The chip equalization technique is one of the important methods that enhance the performance of the high-speed packet transmission in the low spreading factor.For sparse channels, a novel RLS (SMRLS) algorithm is presented.Theoretical analysis and computer simulations show that the performance of the SMRLS is superior to conventional Rake.The new algorithm maintains the steady-state MSE of the conventional MRLS approximately, while the convergence speed is increased and computation complexity is reduced greatly.It proves to be of great value in practical application.

Key words: chip equalization, sparse channels, SMRLS, the 3rd generation mobile communication system
