摘要：

A blind frequency domain method for estimating the propagation delays of DS-CDMA signals is presented. The algorithm is formulated using an antenna array, and uses the fact that the spatially and temporally correlated additive noise, consisting of both interfering users and thermal noise, will be asymptotically uncorrelated on the FFT frequency grid. The algorithm is computationally simple, and can be efficiently implemented using the FFT algorithm. Simulations illustrate that near-far resistance can be achieved using spatial diversity.
