The performance of joint Trellis Coded Quantization/Continuous Phase Modulation (TCQ/CPM) has been investigated. The optimal soft decoding algorithm for the combined TCQ/CPM scheme has been derived and the simulation results show that a large improvement can be achieved when compared with hard decoding. The signal to quantization noise ratio performance for the serially concatenated TCQ CPM system with iterative decoding has also been studied. Numerical results indicate that substantial improvement of performance owing to optimal TCQ based on CPM can be achieved at moderate to high signal to noise ratio on an additive white Gaussian noise channel for a memoryless Gaussian source.
