Performance Evaluation of Differential MSK (DMSK) Systems in an ACI and AWGN Environment

The performance of differential minimum shift keyed (DMSK) systems, with and without nonredundant error correction, is studied. Previous publications described DMSK systems in an additive white Gaussian noise (AWGN) environment. This correspondence presents a study and original performance results of DMSK systems operated in a combined adjacent-channel-interference (ACI) and AWGN environment. Our experimental (hardware) and computer simulation results are found to be in close agreement.
