International Journal puter Applications (0975 –8887) Volume 27–, August 2011 8 Analysis of Channel Coding in Fading Channels for MIMO Systems Umakanta Parida College of Engineering and Management, Kapurthala, INDIA-144601 Sunil Kumar College of Engineering and Management, Kapurthala, INDIA-144601 Omkar Singh Lovely Professional University, Punjab, INDIA-144402 ABSTRACT munication systems are being designed to integrate features that include high data rates as well as high quality of service in the existing communication framework. For this an orthogonal space-time block code (OSTBC) technique improves error performance of synchronous data links without sacrificing data rate or requiring more bandwidth. Trellis coded modulation (TCM) enables efficient transmission scheme and to achieve high coding gain by integrating coding and modulation. In this work an OSTBC concatenated with TCM is implemented for information transmission over different antenna configurations, from Single-Input Single-Output (SISO) to Multi-Input Multi- Output (MIMO) channels. The channel used is a quasi-static Rayleigh fading channel with additive white Gaussian noise (AWGN). The proposed model takes the advantages of the concatenation scheme: the spatial diversity gain offered by OSTBC and the codi
