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.
