Uncoded Cognitive Transmission Over AWGN and Fading Channels

Abstract

In this thesis a new modulation method is studied for an uncoded cognitive transmission (secondary user transmission) in presence of a Primary User (PU) for AWGN and time-varying flat-fading channels. Interference symbol of the PU is assumed to be known at the transmitter of the Cognitive User (CU) beforehand. Based on this knowledge and using a symbol by… (More)
