The Performance of Interleaved BCH (63,39,4) Codes in the Mobile Channel with Four Different Modulations,Two Different Vehicle Speeds

摘要

In this paper, We investigate the performance of interleaved BCH (63,39,4) Code with different interleaving degree applied to a typical VHF mobile fading channel which was modeled by [6] in Johannesburg, South Africa when the subcarrier modulation are FSK 300bits/s, DPSK 1200bits/s, QPSK 2400bits/s and 8PSK 4800bits/s respectively .The research is carried out at two different vehicle speed of 40km/h and lOOkm/h. Some important and significant results for the designs of the error control system in the VHF digital mobile fading channel have been presented.
