Distributed coding for ofdm based cooperative hf radio communication system

Abstract

High frequency (HF) radio system now-a-days used to establish the communication in an area which is isolated from the outside world due to natural calamities. Conventional HF systems are associated with analog voice communication systems; is now shifted to digital voice communication to meet the demands as expected for high data rates for transmission. Cooperative communication is different from conventional relay-assisted HF systems and aims to support the challenging expectation of future generation HF communication systems. Recent days distributed coding is a variety of channel coding developed in a distributed manner for cooperative wireless networks. In this paper we present an overview of various distributed coding design in OFDM based cooperative HF radio communication system.
