摘要
为了有效的抑制多址干扰,该文提出了一种基于次分量分析恒模的多用户检测算法。次分量恒模算法是在恒模代价函数的基础上,推导出一种基于Rayleigh熵形式的代价函数。该文对次分量分析恒模多用户检测算法进行了仿真,并与最小二乘算法和线性约束最小二乘算法进行了性能比较。仿真结果表明,该算法在输出信干比和误码率等性能上都有显著的提高。
For effectively supressing multi-access interference, a new multiuser minor component analysis-constant modulus algorithm （MCA-CMA） was proposed detection method MCA-CMA is an a Rayleigh entropycost function, which is deduced from the traditional CMA error cost function. per simulated and compared the proposed MCA-CMA with the conventional LSCMA and LCLSCMA tion results showed that the proposed MCA-CMA algorithm improved the performance in SINR and rate etc dramatically btsed on algorithm This pa- Simula- bit error rate etc dramatically.
