We assume pilot-symbol-assisted modulation (PSAM) for the estimation of time-varying fading channel coefficients. For the system under consideration, we derive an exact closed-form expression for the average bit/symbol error rate, which is further validated through Monte Carlo simulations. Such closed-form solutions are highly desirable because they allow for rapid and efficient performance evaluation. Through the derived expression, we also demonstrate the effect of various system parameters such as the number of relays, Doppler values, and filter length on system performance.enginfo:eu-repo/semantics/restrictedAccessArticle61139339700030042490003510.1109/TVT.2011.2163536Channel estimationCooperative diversityDecode and forward (DF)Error probabilityPilot-symbol-assisted modulation (PSAM)Time-selective fading channels2-s2.0-84856195838
