Abstract
In the presented work, new companding technique is used to reduce high peak to average power ratio (PAPR) in orthogonal frequency division multiplexing (OFDM) systems. The new companding technique (IMADJS) is used in image processing to do enhancement for pictures. This technique is applied on the OFDM signal to reduce the high PAPR problem. Then, the results of the new technique will be compared with some existing companding methods. The simulation results using Matlab proves that the best results in PAPR, BER and PSD can be achieved by using the new technique (IMADJS)
