The fourth generation mobile communication has used MIMO (Multiple Input Multiple Output) technology to improve system performance. MIMO can be used to get better capacity, coverage, high data rates and throughputs. Land Mobile Satellite (LMS) systems are an important element of the third and fourth generation of wireless systems. In satellite communication system, the use of nonlinear Traveling Wave Tube (TWT) amplifier exhibits severe nonlinear distortions to the transmitted signal, in particular when the TWT works near saturation. As Single Carrier Frequency Division Multiple Access (SC-FDMA) has lower Peak to Average Power Ratio (PAPR) it can be used for uplink satellite communications.
