1-bit quantization and oversampling at the receiver: how to benefit in terms of achievable rate

One challenge in multigigabit per second communication is a fast and energy- efficient analog-to-digital conversion. From communication point of view there are multiple options to relieve the requirements on the analog to digital converter. One specific approach, namely the consideration of oversampling with 1-bit quantization, is investigated in this work with respect to the achievable rate. The presented achievable rates outperform all prior results known from literature on noisy channels with 1-bit quantization at the receiver. It also has been shown, that resolution in time can be superior in terms of achievable rate, as compared to equivalent resolution in amplitude, especially for high signal-to-noise ratio.
