摘要
在介绍码分多址通信系统中2种自适应多址干扰消除算法的基础上,提出一种变步长的自适应并行干扰消除算法。并通过仿真计算,完成了该算法的收敛性、稳态误差性能及系统误码率分析。
A kind of automatic parallel interference cancellation arithmetic is proposed with variable loop,in addition to introducing other arithmetic in CDMA communications. The constringency, error stability and system BER of the arithmetic are validated, which increase the number of users within limited band.
