STBC MC-CDMA系统自适应MBER多用户检测算法
Adaptive MBER Multi-User Detection Algorithm for STBC MC-CDMA Systems
摘要
Abstract
MC-CDMA system has been extensively studied in recent years.Its uplink synchronization model is described using space-time block coding in time-varying multi-path fading environment, and a new multi-user detection algorithm based on minimun bit error rate (MBER)is proposed.By using kernel density estimation and the gradient descent method, an adaptive realization form of the algorithm is deduced.The adaptive MBER detection algorithm for STBC MC-CDMA system with two transmit antennas and two receive antennas is simulated by computer.Simulation results show that the BER performance of this algorithm is very good when the system load is low, and the BER performance declines when the system load is heavy while it is still better than that of the adaptive detection algorithm based on minimum means squared error (MMSE) with similar computing complexity.关键词
