Abstract :
In this paper, the performance of a LMDS (local multipoint distribution service) system with parallel concatenated convolutional coding (PCCC) is analyzed and simulated. The channel of a LMDS system is modeled as a Rician fading channel with strong Rician factor because it is generally accepted that there always exists a line-of-sight (LOS) path between the base station and subscriber units. The performance is evaluated in terms of codeword error probability. From the simulation results, it is confirmed that the performance is significantly improved by employing PCCC. The results in the paper can be applied to the radio modem design of a LMDS system
