Line coded modulation

Abstract

In this paper a new digital passband modulation hierarchy has been proposed. It has the advantage of combining line coding and digital passband modulation in one entity, hence reducing the number of stages of the transmitter and the receiver. The new LCM enhances the transmitted signal with some desirable features such as favorable power spectral density, timing information, error detection and correction, hence, reducing bit synchronization complexity at the receiver, and improving the overall system performance.
