Resumo

Continuous phase modulation (CPM) with 1-bit quantization at the receiver is promising in terms of energy and spectral efficiency. This study proposes a mean square error (MSE) based strategy for selecting the sampling time instances of an oversampled and 1-bit quantized CPM signal. The adaptive sampling scheme is especially suitable for signals with smooth phase transitions such as given by CPM signals based on the raised cosine frequency pulse. Numerical results show that receive processing with the proposed sampling strategy outperforms the conventional receive method based on uniform sampling, while corresponding to a lower computational complexity.
