Abstract: |
The E-band communication system implies high speed pulse shaping filte
r. 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. |
