| Abstract: | In this paper, ade-spread and re-spread smart antenna is designed by using the method of space-time signal processing. Tore duce effective the multipath disturbance and multi-user interference and improve the SNR, time-domain equalizer is employed at the output of each array element of smart antenna. The simulation results show that the performance of the designed antenna is better than the traditional de-spread and re-spread smart antenna. |
