Paper Abstract

In this paper we present advanced modulation and coding techniques for telecommunication systems based on Orthogonal Frequency Division Multiplexing and Radio-over-fiber technologies operating in the subteraherz frequency range 75-110 GHz (W-band). The scheme for the Radio-over-fiber communication system based on full-optical frequency upconversion, and detailed description of the W-band wireless channel are presented. As a result, the main factors affecting the quality of the transmitted radio signal are identified, against which the developed modulation formats are aimed. Improving the efficiency of the Radio-over-fiber system is achieved in two stages: by reducing the interchannel interference due to the windowing of received signal, and reducing the peak-to-average power ratio by precoding the subcarrier frequencies of the group spectrum; by increasing the signal-to-noise ratio when using constellation rotation technique. Obtained simulation results showed that application of the proposed advanced modulation and precoding techniques in Radio-over-fiber systems provides the improvement of energy efficiency and noise immunity.
