摘要 本文针对CDMA系统,提出使用DSP器件ADSP21160实现对感兴趣用户的波达方向和估计的算法。该算法是对传统MUSIC方法的推广与变形,克服了要求接收信号数小于阵元数的局限,算法运算量小,能有效估计CDMA信号的到达方向。 In this paper, the DSP device ADSP21160 is used to realize the estimation of DOA of CDMA signals in CDMA system. The algorithm is a development of traditional MUSIC algorithm, so the number of multipath signals can be most of the array elements and can be used to estimate the parameters of multipath signals.
