摘要/Abstract

摘要： 提出一种带均衡器的解扩重扩智能天线．通过采用参考信号均衡器和时域均衡器使天线阵列主要用于消除多用户干扰而时域均衡器主要用于消除多径干扰训练天线阵列和各均衡器的期望用户信号则由解调出的用户数据重扩产生．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．

Abstract: A novel de-spread re-spread smart antenna with equalizers is proposed．By using a reference signal equalizer and time domain equalizer the antenna array is mainly used to cancel the mult-i user interference while the time domain equalizer is mainly used to cancel the mult-i path interference．The expected user signal for training the antenna array and the equalizers is generated by re-spreading the demodulated expected user data．Simulation results show that the performance of the proposed smart antenna is better than that of the traditional de-spread re-spread smart antennas．

Key words: smart antenna, equalizer, adaptive antenna array, space-time process
