中文说明：该算法是基于基追踪（BP）算法的信道估计仿真，并与传统最小二乘（LS）、MMSE算法仿真作比较，得出其误差和误码率。该仿真采用matlab进行。
English Description：
The algorithm is based on the base pursuit (BP) algorithm of channel estimation simulation, and compared with the traditional least squares (LS), MMSE algorithm simulation, get its error and bit error rate. The simulation is carried out by MATLAB.
