Abstract

Using the high-speed data communication systems, along with the quality of service desirable, is the infrastructure of a command and control system (C41) that should be used in the worst case scenario with the best transmission quality. The use of such a structure in the new defensive systems is very important research topics. As bandwidth increase to increase data rates is costly and sometimes impractical, the use of the orthogonal frequency division multiplexing systems (MIMO-OFDM) The main technology has become the 4G systems. Because of this,         multi-channel systems in wireless systems are used to improve the transmission quality and high-speed telecommunication data, and recently, Frequency-Time-Space Coding (STF) methods have been developed to improve multiplicity interest. The purpose of this paper is to analyze the MIMO-OFDM using a combination of beam shaping and STF techniques. The proposed STFBF method, which combines these two methods, performs better in terms of bit error rates than STF without beamforming and the proposed model is better than the combination of beamforming method and time-space block method (STBC).
