Abstract
Mobility is one of the most interesting assets in modern communications. The need of a very fast data access in wireless communication is become a necessity. It is obligatory to have a good throughput in a wireless limited bandwidth. In this paper we propose to implement a combination of Network Coding and Quadrature Amplitude Modulation (called NC-QAM), started by a simulation and followed by a realization in a Wireless Open-Access Research Platform (WARP) module. Our model consists of two sources and one relay and one receiver. Based on an analytical simulation, theoretically we found that the combination of C-QAM gives us a throughput improvement up to 31.8% compared to QAM without network coding. Based on the same model, the implementation on WARP has been carried-out. Two measurements and evaluations have been performed, with indoor and outdoor channel, by considering distance between two different sources. The evaluation shows that the improvement of combination NC-QAM can reach 14.02% compared to a system without network coding.
