摘　　要： 提出了一种时空联合解扩重扩智能天线。该智能天线在每个阵元输出带有时域均衡器,可以在多径环境下有效消除多径干扰和多用户干扰,提高信噪比。仿真结果表明,该方案的性能优于传统的解扩重扩智能天线。 A de-spread and re-spread smart antenna is designed by using the method of space-time signal processing. To reduce 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.
