“…HQAM has the densest 2D packing with optimum Euclidean dual-hop cooperative variable-gain AF relaying network, over mixed Nakagamim/Rician fading links. In [33], comparative analysis of BER for the OFDM based dual-hop cooperative network is carried out for various fading channels. However, power allocation and performance analysis is carried out in [34], for a multi-hop and multi-branch cooperative AF relaying network over generalized channel models.…”
