| Abstract: | Surface asoustic wave (SAW) filter is used directly as symbol-shaping filter and modulater, the truncated cosine series function has been applied to synthesize this FIR filter and the critera which govems the selection of the coefficients are given. Author propose a novel design and optimization mehtod which uses the standard Remez change algorithm with the help of rersample and interpolation reconstuture for the practical SAW filter with multistrip coupler. The simulation results confirm this algorithm is very effective nd simple. |
