D-MG Tradeoff of DF and AF Relaying Protocols Over Asynchronous PAM Cooperative Networks

The diversity multiplexing tradeoff of a general two-hop asynchronous cooperative network is examined for various relaying protocols such as Non-orthogonal Selection Decode-and-Forward (NSDF), Orthogonal Selection Decode-and-Forward (OSDF), Non-orthogonal Amplify-and-Forward (NAF), and Orthogonal Amplify-and-Forward (OAF). The transmitter nodes are assumed to send Pulse Amplitude Modulation (PAM) signals asynchronously, in which information symbols are linearly modulated by a shaping waveform to be sent to the destination. The authors consider two different cases with respect to the length of the shaping waveforms in the time domain.
