Performance analysis of cooperative HADF relaying V2I communication systems for ND-symbol burst transmission using PSA-CE methods over quasi-static rayleigh fading channels

In this paper, we derive the average symbol error rate (SER) for the N_D-symbol burst hybrid adaptive decode-or-amplify-forward (HADF) relaying vehicle-to-infrastructure (V2I) communication systems over quasi-static independent and non-identical distributed (INID) Rayleigh fading channels. Our proposed analytical approach includes channel estimation (CE) errors generated by practical pilot symbol assisted-CE (PSA-CE) schemes. Firstly, based on the error-events at relaying on board equipments (OBEs) for N_D-symbol burst data transmission, the conditional SER expression has been derived as an exact form. Then, the approximated average SER (ASER) expressions are presented as the closed-forms and their accuracy is confirmed by the comparison with simulation results. Therefore, we can conclude that our analytical expressions are tractable forms, and can be used as a tool to verify effects of an erroneous detection and hybrid transmission at each relaying OBE on the combined signal-to-noise ratio (SNR) and ASER for cooperative HADF relaying communication systems.
