Peak-to-Average Power-Ratio Reduction Scheme Employing Fountain Codes.

New peak-to-average power-ratio (PAPR) reduction scheme for multiuser CDMA systems are developed by employing fountain codes. In the proposed scheme, the transmission data is encoded by the fountain code. The encoded data is discarded at the transmitter if the PAPR exceeds the specified threshold, and at the same time another encoded data will be created. In consequence, the PAPR is dominated below the threshold. From the simulation methods, we find that the proposed scheme can reduce the PAPR with no degradation on the performance.
