Based on the RLS algorithm, a multi-element uniform linear antenna array algorithm is proposed by using DSP and distributed shared memory. The fundamental and some characteristics of the proposed algorithm are briefly discussed. And then aimed at the characteristic of TMS320C6416 digital signal processor and the convergence capability of RLS - based algorithm, the realization of this smart antenna algorithm and the optimization algorithm are discussed. Simulation shows that this algorithm meets the real - time requirements of 16 element uniform linear antenna array that 2048 point 8 bit 8 KHz sampling.
