Abstract :
In this paper we consider the case of an oversampled exponentially modulated transmultiplexer. We particularly focus on the interference created by a time offset impairment. We, firstly, simplify the expression of the Signal to Interference Ratio (SIR). Then, using this SIR expression as the optimization criterion, we provide perfect (PR) and nearly perfect (NPR) solutions that all outperform conventional OFDM.
