In this paper, the diversity gain of a Maximal Ratio Combiner (MRC) has been investigated for Orthogonal Frequency Division Multiplexing (OFDM) by varying the number of receiving antennas. technique has been presented in this paper. It is also shown that SNR can be improved further if the number of receiving antennasis increased.
Mobile Ad hoc Networks (MANETs) have drawn considerable attentions of the researchers for the last few years. MANETs, consisting of mobile nodes, are self-organizing and self-configuring and hence can be deployed without any infrastructure support. MANETs also have some limitations including short-life, unreliability, scalability, latency, high… (More)
Wireless communications are subject to three major constraints: (i) a complex and unpredictable fading channel, (ii) a scarce radio spectrum, and (iii) limitations on the power and the size of handheld terminals. New technologies have been introduced and evolved based on these constraints. Among all of these technologies Worldwide Interoperability for… (More)
