| Abstract: | Inter-symbol interference(ISI) and frequency width expanding can be avoided by pulse shaping technique in most communication system. The multi-phase structure filter needs less multiplication operations comparing with some other FIR filter and it's a good choice for pulse shaping implementation.A pulse-shaping scheme based on multi-phase filter using TMS320C5402 is presented in this paper.Some key points for debugging are described. |
