摘要：
High value of P APR and Inter-carrier Interference are two main drawbacks of the orthogonal frequency division multiplexing (OFDM) based wireless systems. The problem of high value of P APR has been addressed in this work. A novel companding technique is proposed to reduce the PAPR of OFDM signals. The general analytical model for this novel scheme has been obtained and the results obtained after simulation proves that the proposed method has significantly improved the performance in the terms of BER and PAPR reduction as compared to mu-law and exponential companding. To fulfill various design requirements, the selected companding techniques parameters can also be changed to achieve a better tradeoff between BER and PAPR reduction.
