Cooperative Communication in UWB OFDM Systems
Journal Title: International Journal of Engineering and Science Invention - Year 2017, Vol 6, Issue 11
Abstract
Ultra Wide Band (UWB) technology is a fast emerging technology for short distance wireless communication. UWB plays a preeminent role in the short range wireless systems, due to the advantages of high speed, low power consumption and very high security. Methods/Statistical Analysis: With cooperative communication as a decisive member in its side this paper proposes cooperative MB-OFDM communication using effective grouped relays in multichannel with use of Dual Carrier Modulation (DCM) for UWB systems. We can attain maximum diversity by using simple Maximum Likelihood (ML) receiver without reduction of data rate as its found using almounti coding which is most used to provide diversity in cooperative communication. Findings: The Proposed method’s resulting diversity is observed using outage probability as a basic parameter and also how the outage probability varies in accordance to threshold power. Application/Improvements: The results shows an improved BER versus SNR with effect of CFO is considered and the improvement in channel capacity and data rate of various different modulation schemes is obtained by varying SNR and distance.
