Abstract

Orthogonal Frequency Division Multiplexing (OFDM) technology is one of the most recent emerging trends in Wireless Communication. The major disadvantage of OFDM system is the high Peak-to-Average Power Ratio (PAPR) which result in the Bit Error Rate (BER) performance degradation. In this paper, a Low-Density-Parity Check (LDPC) encoder is used effectively to reduce PAPR problem. In addition the Multiple-Input Multiple-Output (MIMO) antennas technology is studied to solve reception problem.The reviewed techniques shows better reduction in PAPR as compare to other techniques, such as Cyclic coding, selective mapping, filtering and clipping
