A Closed-Form BER Expression for Decode-and-Forward Cooperative Communication Protocol
Hyung-Yun Kong · Journal of electromagnetic engineering and science · 2009
The decode-and-forward cooperative communication protocol allows single-antenna users in wireless environments to obtain the powerful benefits of multi-antenna systems without the need for physical arrays. Evaluating the performance of this protocol through simulations is time-consuming and therefore, a need exists for an analytical BER expression to serve as a reference. This paper proposed such an expression for coherently BPSK-modulated data.
