Paper Abstract

We present a constant amplitude multi-code (CAMC) CDMA in a recursive structure which has a built-in error correction capability. The PAPR of CAMC is very low since the amplitude has a constant value, which is accomplished at the cost of redundant bits for the precoding in CAMC. We show, however, that redundant bits in CAMC can be reconfigured into parity bits in a single parity check product code (SPCPC). An iterative decoding algorithm is presented which fully utilizes the parity bits of the reconfigured CAMC. Experimental results show that CAMC has a superior performance of error correction than a generic SPCPC.
