本文针对CDMA 系统，提出使用DSP 器件TMS320C6701 实现对CDMA 信号的波达方向估计。该算法基于对解扩前后相关阵相减，去除了干扰相关阵是，然后使用传统MUSIC或ESPRIT 算法进行DOA 估计，克服了要求接收信号数小于阵元数的局限，能有效估计波达方向相差很小的多径信号的参数。关键词：CDMA；波达方向（DOA）；TMS320C6701；相关阵Abstrat: In this paper, the DSP device TMS320C6701 is used to realize the DOA estimation of CDMA signals. The algorithm is based on the matrix before and after correlating. For such an algorithm, the number of multipath signals can be most of the array elements and can be used to estimate the parameters of multipath signals.Key words: DOA, DSP, TMS320C6701, correlation matrix.
