【摘要】：根据快速滤波器组所具有的级联结构、良好频率选择性以及低复杂度的特点,提出了一种多通道同步接收机的设计方法来并行处理多路接收信号.该方法将最小化系统所需乘法器的总数量作为目标函数,以通带和阻带所允许的纹波作为约束条件,设计各级原型滤波器的脉冲响应系数,以满足接收机各通道全局设计指标的要求.以工作频率为88~108 MHz的调频广播信号并行解调系统作为仿真和实验平台对该方法进行验证.结果表明,所提出的设计方法能够满足多通道同步信号处理的要求,且每个通道所需乘法器的数量大约为加权重叠(WOLA)滤波器组方法所需乘法器数量的66.4%,具有较低的实现复杂度.
[Abstract]:According to the cascade structure, good frequency selectivity and low complexity of fast filter banks, In this paper, a design method of multi-channel synchronous receiver is proposed to process multi-channel signals in parallel. The method takes the total number of multipliers required for minimizing the system as the objective function, and takes the ripple allowed in the passband and stopband as the constraint condition. Design pulse response coefficients of prototype filters at all levels, In order to meet the requirements of the global design of the receiver channels, the parallel demodulation system for FM broadcast signals with a working frequency of 88 ~ 108 MHz is used as a simulation and experimental platform to verify the method. The results show that, The proposed design method can meet the requirements of multi-channel synchronous signal processing, and the number of multipliers required for each channel is about 66.4 of the number of multipliers required for weighted overlapping WOLA-filter banks, which has a lower implementation complexity.
