Modulation, coding, and synchronization techniques for nano-electromagnetic communications in terahertz band

Abstract

This chapter aims to provide insights into the modulation and coding schemes (MCS) tailored for-and synchronization issues faced by-the nano-scale electromagnetic communication systems operating in the terahertz (THz) band. The MCS is of paramount importance for the works dealing with rate and power adaptation by the transmitter when channel state information at transmitter (CSIT) of the link is available. Synchronization, on the other hand, refers to frequency, phase, and timing synchronization and is the pre-requisite for many modern signal processing operations, advanced multi-antenna techniques, and advanced modulation techniques. Some prominent examples that require synchronization include decoding at the receiver, multi-input, multi-output (MIMO) systems, beamforming, and orthogonal frequency division multiplexing (OFDM).
