Popis: Space frequency block code orthogonal frequency division multiplexing (SFBC-OFDM) systems has inherit drawbacks of high peak-to average power ratio (PAPR) signals, and constellation shaping with trellis is a promising approach for reducing both peak power and bit error rate of SFBC-OFDM signals. In practice, reliability will improve in SFBC-OFDM by employing coded modulation. In this work, it has been proposed two trellis coded mapping method for SFBC MIMO OFDM system for achieving good error performance as well as reduced PAPR and compared with SLM technique.Based on the simulation results the proposed methods has the capability to provide reduced PAPR and bit error rate in SFBC MIMO-OFDM systems without side information.
