Abstract

We investigate the design of an interpolation filter of a multi-frequency TDMA (MF-TDMA) demodulator which is applied to DVB-RCS. If sampling is not synchronized to the data symbols, timing adjustment in the digital receiver must be performed by interpolation. It is impossible that conventional ideal (sinc) interpolation filter coefficients are actually extended to infinity. We propose a Kaiser window interpolation filter and a sinc interpolation filter using the Kaiser window. Simulation results show that the performance improvement is realized by employing the proposed (optimal) interpolation filter.
