| Abstract: | In this paper, we investigate the performance of BCH (63 39 4) Code, BCH(127 78 7 ) codeand BCH(127 64 10) code with different interleaving degrees applied to the VHF mobile channel which was modelled by Swarts et al. in Joharmesburg, South Africa when the suhcdrier modulations are FSK 300bits/s, DPSK 1200bits/s, QPSK 2400bits/s and 8PSK 4800bits/s respectively at two different vehicle speeds of 40km/hand 100km/h in two different communication environments -city environment and freeway environment. |
