Abstract

We present an error-correction coding scheme for mobile digital code division multiple access (CDMA) communications. The code construction is based on the idea of generalized concatenated coding and assumes a non-coherent detection at the receiver. Such a condition is e.g. given in the reverse link of the IS-95 system. We use a first-order Reed-Muller (RM) inner code and terminated convolutional outer codes. For comparison purposes, the code employed in the reverse link of IS-95 is used as the reference code
