Outage Probability of Multihop Communication System with MRC at Relays and Destination Over Correlated Nakagami-m Fading Channels

This paper analyzes the outage probability of a multihop transmission link with the maximal ratio combining (MRC) diversity technique associated at the intermediate relays and the destination. The exponential and equal correlation models are considered among the input receiving antennas of MRC diversity reception at the relays and end user. The source node is assumed to have a single antenna for transmitting the signal to the node at destination. The source node transmits the signal through decode and forward type of relay nodes to the destination node. The exact-form explanations have been acquired for the outage probability of the system considering the communication through Nakagami-m wireless fading channels with two correlation models. The response of correlation at the outage probability presentation is analyzed. It is noticed that outage performance degrades with an increase in correlation for both cases. The consequence of outage probability for separate stages of fading parameter, diversity order, and the different number of hops has been observed.
