Zhong Wen · Telecommunication Engineering · 2013
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 f ilter 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 f ilter can decrease 21% of the multiplications and 13.4% of the delays,and fulfills the E-band system demands with 6-bit quant ization.
