Optimization of the Complex Filter Bank and Its Application in the Communication System

文章提出了一种生成复数滤波器组的优化算法,给出了基于复数滤波器组调制的通信系统的模型。仿真结果表明,通信系统采用优化生成的复数滤波器组调制时的性能比采用对比的复数滤波器组调制时的性能好,且当采用双天线分集接收时,系统误比特率性能得到进一步改善。

This paper proposes an optimizing algorithm of the complex filter bank and gives its application model on the communication system. The simulation results show that the new system, which is based on the optimized bank modulation, outperforms the analogy system based on the usual complex filter bank modulation. This is especially true when the proposed system takes on a much - improved performance in the employment of a double antenna reception diversity.
