摘要:
为了获得性能高复杂度低的抗多径衰落接收机,该文将快速近似幂迭代(Fast approximated power iteration,FAPI)子空间跟踪算法应用到Rake接收机中,实现一种新型的自适应Rake接收机。采用Rake接收机来消除码分多址通信系统中多径衰落,利用FAPI算法实现对信道参数的精准估计,从而进一步改善了Rake接收机的误码率性能。同时,由于FAPI算法的低复杂度,该文所提出的新型Rake接收机也具有复杂度低的特点。实验仿真结果表明:FAPI Rake接收机是一种高性能低复杂度的抗多径接收机。
Abstract:
To get an anti-multipath receiver with better performance and lower complexity,a new Rake receiver is put forward in this paper which uses fast approximated power iteration(FAPI)subspace tracking algorithm.Rake receiver is used to eliminate multipath fading in code division multiple access,and FAPI is used to estimate channel parameters accurately.Because FAPI has low complexity,the new Rake receiver has low complexity too.The simulation results show that the FAPI Rake receiver is an anti-multipath receiver with better performance and lower complexity.
