Abstract

Communication is one of the important aspects of human life. With the advancement in age and its growing demands, there has been rapid growth in the field of communication. Multi-carrier modulation is an attractive transmission technique for fourth generation high speed wireless communication. Orthogonal Frequency Division Multiplexing (OFDM) is a promising multicarrier technique used in wireless communication with high data rate and high spectral efficiency.One of the main problems of the OFDM system is the high Peak-to-Average Power Ratio(PAPR) of transmission signal due to the use of many subcarriers. In this paper, a joint Discrete Cosine Transform (DCT) and µ-law companding method is proposed to reduce peak-to-average power ratio of OFDM signal. Simulation results show that this new method is more efficient than the conventional OFDM systems.
