A new approach on delay coding: the receiver [articol]

Abstract

This paper represents the second part of an issue from the "Communications 2004". Now, herewith we are presenting the receiving part following the idea to see the Delay Coded Signal DCS as a QAM signal, namely a Vestigial SideBand VSB one. One uses the fact that the DCS is a four phase signal, rotating 0⁰/90⁰ clockwise. The demodulated signal is ternary too and alternating on the two branches, elsewhere identical. The carriers have half the signaling rate frequency. One expose three demodulation methods and two probability density functions together with the simulation results.
