摘要
This paper introduces throughput-efficient wireless system based on an extension to binary phasemodulations,named extended binary phase shift keying(EBPSK),and the corresponding analysis ofpower spectra,especially the extension to channel capacity are given.Importantly,a novel sequential es-timation and detection approach for this EBPSK system is proposed.The basic idea is to design a proba-bilistic approximation method for the computation of the maximum a posterior distribution via particle fil-tering method(PF).Subsequently,a new important function in PF is presented,so that the performanceof the detector has a great improvement.Finally,computer simulation illustrates that EBPSK system hasvery high transmission rate,and also the good performance of the proposed PF detector is demonstrated.
This paper introduces throughput-efficient wireless system based on an extension to binary phase modulations, named extended binary phase shift keying （EBPSK）, and the corresponding analysis of power spectra, especially the extension to channel capacity are given. Importantly, a novel sequential estimation and detection approach for this EBPSK system is proposed. The basic idea is to design a probabilistic approximation method for the computation of the maximum a posterior distribution via particle filtering method （PF）. Subsequently, a new important function in PF is presented, so that the performance of the detector has a great improvement. Finally, computer simulation illustrates that EBPSK system has very high transmission rate, and also the good performance of the proposed PF detector is demonstrated.
