In this paper, we present the performance evaluation of coded wireless ad-hoc network for emergency response communication. Due to the limited transmission range, a number of intermediate relaying nodes may exist between source and destination and these convey source transmission using hybrid Amplify-and-forward (AF)/Decode-and-forward (DF) protocol. All nodes contain single antenna and OFDM based...
The vast acceptance of OFDM technology is not limited to the radio domain, but is also among researchers for wireline and wireless optical communications. For indoor wireless optical communications, the use of OFDM faces a major challenge in reducing the average transmit optical power to cope with the eye safety problem. We propose the use of the selected mapping (SLM) technique to reduce the average...
It is becoming increasingly difficult to satisfy the growing demands on spectrum with the conventional policy of fixed spectrum allocation. To overcome this problem, flexible and dynamic spectrum sharing methods that can significantly improve utilization of the spectrum have gained increasing interest recently. In this paper, resource allocation in decentralized spectrum sharing systems applying the...
