The Cost

In this paper, based on the research of the Continuous Phase Modulation (CPM) receiver, we conclude that the coherent demodulation can achieve better frequency efficiency than the non-coherent demodulation, at the cost of higher design complexity. Hence, this paper proposes a novel differential soft decision scheme to reduce the complexity of the CPM receiver. Simulation results show that the proposed scheme can reduce the complexity of the CPM receiver significantly, while causes a slight performance loss

In this paper, continuous phase modulation (CPM) with rate-compatible punctured ring convolutional codes is investigated. Some typical schemes with maximum normalized minimum squared euclidean distance (NMSED) are searched and given. The performance of bit error rate for rate-compatible punctured ring convolutional coded CPM on AWGN channel is simulated, and simulation results show that this system can provide good performance of bit error rate and variable-rate capabilities. Furthermore, simulation results also prove that the transmission efficiency increases when code rate is decreasing.
