The Potential of Continuous Phase Modulation for Oversampled 1-Bit Quantized Channels

摘要

We study the achievable rate of a 1-bit quantized temporally oversampled AWGN channel using continuous phase modulation schemes. Given a requirement for very high data rate, 1-bit quantization could become a key component to increase the energy efficiency in future communication systems since it greatly relieves the hardware requirements at the receiver. Due to its constant envelope, phase modulation furthermore relaxes the requirements on the transmitter architecture. We investigate the potential of continuous phase modulation and show that in order to approach the full potential of continuous phase modulation under 1-bit quantization, a tailored waveform design is required.
