Optimal Codeword Design for Precoded UWB (PUWB) Systems
Abstract— A precoding technique applied to symbols transmitted in an ultra-wideband (UWB) system was proposed in [1], which can concentrate the signal power at the receiver to fa...

Block Detection of Multiple Symbol DPSK in a Statistically Unknown Time-Varying Channel
—We present a detection scheme for multiple-symbol DPSK for use in a statistically unknown time-varying channel. The scheme relies on a parametric representation of the timevaryi...

Spectrally efficient noncoherent communication
This paper considers noncoherent communication over a frequency-nonselective channel in which the time-varying channel gain is unknown a priori, but is approximately constant over ...
