System Design and Analysis of MIMO STBC -OFDM System With or without clipping technique

In current communication 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 multipath Rayleigh fading channels with bpsk modulation , in deffrent antenna selection techniques, and with or without papr reduction technique (clipping) .
