ERROR-CORRECTING CAPABILITY OF CONSTANT AMPLITUDE CODING FOR ORTHOGONAL MULTI-CODE CDMA SYSTEMS

In this paper, we discuss the error correcting capability of the const ant amplitude coding. In orthogonal multicode CDMA systems, the transm itted signal has large amplitude fluctuation and the amplitude fluctua tion causes large nonlinear distortion. In order to avoid the amplitud e fluctuation, we have proposed ''constant amplitude coding'' in our p revious study. The constant amplitude coding can achieve constant ampl itude transmission by utilizing the redundancy of the coding, i.e., th e coding can have an error correcting effect. In this paper, we examin e the effectiveness of the error correcting capability of the constant amplitude coding and show that the constant amplitude coding is very effective against nonlinear distortion under the consideration of the error correcting capability.
