Abstract

By combing SM with the amplify-and-forward (AF) cooperative communication, the cooperative SM scheme with AF (AF-SM) is presented for obtaining superior performance. The bit error rate (BER) performance of AF-SM is investigated over Rayleigh channels. According to the performance analysis, a tightly upper bound of the output SNR is given, and the corresponding probability density function (PDF) is derived by means of the moment generating function (MGF). Based on the obtained PDF and MGF, the error probability of antenna index estimation (Pa) and the error probability of symbol estimation (Pd), which constitute the overall average BER, are derived, respectively. As a result, tightly approximate closed-form expressions of the Pa and Pd are obtained, respectively. With these expressions, the closed-form BER is achieved. These theoretical expressions can match the simulations well, and thus the BER performance of AF-SM can be effectively evaluated. Simulation results verify the effectiveness of the theoretical analysis, and the BER performance can be improved by increasing the receive antennas.
