Performance Analysis of Turbo Code Concatenated with STBC Over Land Mobile Satellite Communication Channels

摘要

In this paper, Turbo code concatenated with STBC has been employed in land mobile satellite communications characterized by Lutz model deemed to be one of the most significant statistical approaches of communication. Land mobile satellite communication massively requires considerable reduction in bit error rate for low SNRs as well as great diversity and coding gains due to the fact that transmitted signals have to overcome great amount of turbulence effects as well as other destructive effects through communication. Initially, we have presented an overall review of Turbo, Space time block codes (STBC) and Lutz model, the former as two different coding schemes which could be taken in to account to combat the fading effects in the satellite communications and the latter as a two-state Markov model applied in land mobile satellite communication channels. Employing foregoing structure could lead to reliable transmission as well as considerable bit error reduction.
