摘要：This paper briefly discussed the principle of the linear constraints minimum variance (LCMV) algorithm and the least mean square (LMS) algorithm on the basis of the construction of an uniform circular antenna array. Then it compared the parameters of the two, such as signal-to-noise ratio, bit error rate, the average error, convergence rate, and so on, and then it was simulated by MATLAB. The simulation results showed that performances of LCMV algorithm were a little bit worse than LMS algorithm when interference was relatively strong, but much better than LMS when SNR was above 0dB. At last, we found out the appropriate algorithm for each environment, and proposed the improvement measures.
