Low-complexity multiuser receiver scheme for STC-CDMA communication system and its performance analysis
چکیده انگلیسی

By utilizing the complex orthogonality of space–time coding, a multiuser receiver scheme is proposed for full-diversity space–time coded CDMA systems for effective decoding. The scheme can reduce the high decoding complexity of the existing scheme greatly, and achieve low calculation complexity. Based on the system symbol error rate (SER) analysis and moment generation function, the average SER and bit error rate (BER) are derived in detail, and the high-accuracy approximate expressions are obtained. With these expressions, the system performance can be effectively evaluated in theory. Simulation results show that the proposed receiver scheme performance is very close to the existing scheme performance, the derived SER and BER expressions can match the simulated values well, and thus the validity of the theoretical analysis is verified.
