Orthogonal Frequency Division Multiplexing (OFDM) is a very attractive technique for high-data-rate transmission in wireless and wired applications. The main drawback of the OFDM technique is its high peak to average power ratio(PAPR). Several approaches exists to reduce PAPR of OFDM symbols. Precoding is a new method which is having less complexity compared to the other power reduction techniques and also it can reduce PAPR considerably and results in no distortion. Error control

... tion coding is used here) can also be introduced along with the Precoding technique in order to improve the bit error rate performance. Clipping and filtering with bounded distortion is a simple method and provides a high PAPR reduction at the cost of signal distortion. we can restrict this distortion within a particular limit using bounded distortion algorithm(BD). In this paper the PAPR reduction is obtained by combining the precoding method and clipping technique with BD i.e. this modified method takes the advantages of two PAPR reduction technique. This paper presents various computer simulation results to verify the effectiveness of this modified precoding method.
