An improved multi-user detector in UWB communication system

Aiming at the problem of multi-user detection in Ultra Wideband (UWB) communication system, an improved multi-user detector with Quantum Discrete Particle Swarm Optimization (QDPSO) is proposed, which effectively combines quantum computing and intelligent computing in detection algorithm, takes advantage of the user information to detect the target user's data, to achieve the best possible detection results. Through study of the bit error rate (BER) performance on the detection algorithms with different parameters, and comparison on the three kinds of multi-user detectors in BER performance, the results show that the multi-user detector with QDPSO algorithm is superior to the multi-user detector with Discrete Particle Swarm Optimization (DPSO) algorithm and the traditional detector.
