建立了一种空时信号传输模型，分析对比了递归最小二乘（RLS）和最小均方误差（LMS）两种算法后，提出了一种基于RLS算法，由智能天线和时域均衡器组成的采用后馈滤波器的空时联合均衡器。仿真结果表明，在多径衰落信道下该方法能有效改善系统抗干扰能力，算法简单且易于实现。

针对TDMA/TDD公众蜂窝移动通信系统的特征，运用了一种智能天线的解决方案，研究并提出一种动态时隙指派的算法。目的是让无线资源指派根据空时最佳特性进行量化评估并优选，然后把最优载波和时隙分配给需要的移动终端。系统级仿真表明，本算法和传统时隙分配算法相比，移动通信网络的综合性能指标得到的显著的改善。

Interference cancellation is made available by using smart antenna at cellular base stations. Well-distributed cumulative probability of signal-to-interference plus noise power ratio appears to be vital for cellular mobile multimedia communications. A scenario of dual links dynamic power control combined to a solution of smart antenna is proposed to adjust the instant transmission power in terms of the disparity from the favorite range. Simulation results show that this method is quite effective to improve the cumulative distribution probability performance. Meanwhile, accompanying low power consumption is also obtained at both base stations and mobile stations.

In high-speed multimedia mobile communications, when multi-path signal arrive at the antenna, different time delays must exist among different paths, which bring about Inter-Symbol Interference (ISI). Therefore, the technique called temporal equalizer for 8-element adaptive array antennas (AAA) is studied in this paper. This technique is realized through landscape orientation filter, whose weight vector is formed by RLS algorithm. AAA is only employed on base station, meanwhile, transmitting downlink signal with a simple way. Computer simulation runs in the environment with TDMA/TDD frame structure. The result shows that the BER value is improved and the performance is better than ever.
