Abstract
This paper presents the performance of a new cooperative relay protocol in mobile network over Raleigh environment. Characteristically, the 5G network at 28 GHz covers short distances due to its shorter wavelength. Extending network coverage area and improvement of signal quality is a necessity. In this work, high performance hybrid relay nodes were proposed to improve quality of the signal and increase the signal coverage distance. Mathematical expression was successfully derived for new hybrid decode amplify forward (HDAF) protocol. The destination node combines received symbols from hybrid relay nodes and source node using maximal ratio combiner (MRC) for optimal performance. The performance of the developed model was evaluated using bit error rate (BER), outage probability (Pout) and processing time (Ptime) at different signal to noise ratio (SNR). Comparatively the developed HDAF protocol performed better than DF and AF by having a lower BER, Pout and Ptime values. The result also shows that HDAF relay protocol has the potential to mitigate signal interference and extend the coverage area in 5G network.
