摘要
为实现E-band(E频段)通信系统中的高速成形滤波,在已有快速FIR滤波算法(FFA)基础上,通过快速短卷积迭代以及张量展开算法,设计了一种高速并行FIR成形滤波器,并进行硬件复杂度分析与时延分析。浮点和定点数仿真验证结果表明,所设计高速并行滤波器在硬件实现上可减少21%的乘法运算操作和1314%的时延单元,6比特以上小数量化可达到系统成形滤波需求。
The E-band communication system implies high speed pulse shaping filter. On the basis of fast FIR (Finite Impulse Response) algorithm (FFA) and fast iterated short convolution algorithm, a parallel FIR shaping filter is designed. The hardware-complexity and time-delay performances are analyzed,and the filtering properties are verified according to both floating point and fixed-point simulation. The parallel FIR filter can decrease 21% of the multiplications and 13.4% of the delays, and fulfills the E-band system demands with 6-bit quantization.
