On the Error Rate Analysis of Dual-Hop Amplify-and-Forward Relaying in Generalized-K Fading Channels

Figure 2

Average SER for 4-PSK versus average SNR per hop for 𝑁=1 and 𝑁=2 dual-hop links with MRC assuming 𝑚₀=1,𝑘₀=0.5 for the direct link, 𝑚₁=1,𝑘₁=1.5 for the first relay link, and 𝑚₂=2,𝑘₂=3 for the second relay link.
