On the Capacity of Waveform Channels Under Square-Law Detection of Time-Limited Signals
arXiv:2001.08138 · doi:10.1109/TIT.2020.2999889
Abstract
Capacity bounds for waveform channels under square-law detection of time-limited complex-valued signals are derived. The upper bound is the capacity of the channel under (complex-valued) coherent detection. The lower bound is one bit less, per dimension, than the upper bound.
