This paper shows the analytical performance expressions of M-ary quadrature amplitude modulation burst symbol transmission for hybrid decode-or-amplify-forward (HDAF) relay schemes over quasi-static Rayleigh-fading channels. First, we derive the probability density function of the received instantaneous signal-to-noise ratio as the simplified form, which is related to all the possible occurrence probabilities of error-events for M-ary quadrature amplitude modulation burst transmission. On the basis of the derived probability density function, we express average bit error probability, average symbol error probability, and average burst error rate as closed forms, which can be also applied to both amplify-and-forward and adaptive decode-and-forward (ADF) schemes. The analysis and simulation results show that HDAF scheme for burst transmission can achieve the performance of ADF scheme with symbol-by-symbol transmission, which is the achievable lower bound. Furthermore, the outage probability, the normalized channel capacity, and the goodput performance are also derived as closed forms. The analysis shows the superiority of HDAF scheme to ADF scheme. Comparison with simulations confirms that the derived analytical expressions are accurate over all signal-to-noise ratio regions and for different numbers of relays and modulation orders.

SUMMARYThis paper analyzes averaged symbol error probabilities of burst transmission consisting of pilot and data symbols for hybrid adaptive decode-or-amplify-forward (HDAF) relaying systems. Under the assumption of quasi-static Rayleigh fading channels with independent and non-identically distribution, we consider a channel estimation scheme based on pilot symbols and show how channel estimation error affects received signal-to-noise ratio (SNR) and symbol error probability (SEP). Firstly, all the possible detection error-events are presented for all the relay nodes, and their probabilities are derived as forms related with data symbol burst transmission. For the given error event, we analyze the conditional SEP as an exact form and then, the averaged SEP (ASEP) is approximately derived as a closed-form. The simulation results verify that our derived ASEP expression is accurate over all the regions of SNR. Utilizing the proposed expressions, we can evaluate ASEP performance of HDAF relay systems easily and fast.
