摘要
本文在文献[7]基础上研究了采用分组BCH码加交错技术抗衰落的性能．模拟了：BCH（63394）码、BCH（127787）码和BCH（1276410）码在交错与非交错两种不同情况下，副载波调制方式分别FSK300bits／s、QPSK1200bits／s、QPSK240bits／s和8PSK4800bits／s。
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.
