Performance Analysis of STBC- OFDM System Under Multipath Fading Channel

In current 4G systems growing demand of multimedia services and the growth of Internet related contents lead to increasing interest to high speed communications. Recently, Space Time Block Codes (STBC) have gained much attention as an effective transmit diversity technique to provide reliable transmission with high peak data rates to increase the capacity of wireless communication systems. In this paper, performance of STBC-OFDM is analyzed under different constraints in Rayleigh fading channels. The authors have studied the effect of modulation order, antenna selection techniques, slow and fast fading conditions and power conditions on the performance of STBC-OFDM.
