摘要
智能天线技术在未来无线遥测系统中有很广阔的应用前景。对PCM/FM智能天线遥测系统进行了仿真分析,为未来智能天线无线遥测系统的设计提供了一定的理论基础。首先对PCM/FM系统建立了信号仿真模型,然后提出了一种基于RLS-CMA和MLMS-CMA算法的混合数字波束形成方案,最后在4阵元均匀线阵下对系统进行了仿真分析。结果表明,在无线遥测系统中采用智能天线技术,能够有效地提高系统的信噪比,改善系统的误码性能。
Smart antenna technology will be widely used in telemetry systems in the near future. Some simulation analysis for PCM/FM telemetry systems with smart antennas was made. Firstly, signal simulation models were established for PCM/FM systems. Secondly, a hybrid digital beam-forming scheme based on RLS-CMA and MLMS-CMA was developed. Finally, simulation analysis was made for a uniform linear array with four elements. The results show that while introducing smart antenna technology in wireless telemetry systems, it can efficiently raise signal-to-noise ratio and improve bit error rate performance of the system.
