This paper presents a closed form expression for the theoretical BER of decode-and-forward (DF) relaying over time selective fading channels. In our derivation, DBPSK is chosen as a modulation scheme and radio channels between nodes are assumed to be different time selectivity and therefore, the proposed theoretical formula provides the BER at any arbitrary Doppler effect due to the mobile nodes. The validity of the proposed theoretical approach is confirmed by comparing with the computer simulation results.
