    Detection of 3D Spatial-Temporal Spectrum Opportunity in Satellite-Terrestrial Integrated Network by Ning YANG, Daoxing GUO

    Published 2022-12-01
    “…The detection of 3D spectrum opportunities in the downlink sharing scenario in satellite-terrestrial integrated networks was investigated.First, defined the 3D space-time spectrum opportunities in the satellite-terrestrial integrated networks, and further divided the opportunities into three areas in the spatial domain: the communication area of primary user, the communication protection belt, and the free access area.Then, based on the proposed 3D opportunity model, derived the closed expressions of the detection and false alarm probability at the user-level and the network-level, respectively.In order to further utilized the spatial spectrum opportunity, a power control scheme of the cognitive user was determined through 3D spectrum sensing, i.e., interference constraint (IC).The simulation results demonstrated that the proposed power control scheme could realized the detection of 3D spectrum opportunity.…”

    Multiple access based on three-stage modulation in multi-band OFDM-UWB system by BAO Zhi-hua, ZHANG Shi-bing, ZHANG Guo-an, QIN Jin-jing

    Published 2007-01-01
    “…According to the characteristics of multi-band orthogonal frequency-division multiplexing ultra-wideband(OFDM-UWB) system,a multiple access based on three-stage modulation(TSM-MA) was proposed.It combined multi-carrier code division multiple access(MC-CDMA) with orthogonal frequency division multiple access(OFDMA) and frequency hopping multiple access(FHMA),carried out the advantages of the three multiple access techniques.It reduced the multiple access interference and made full use of the available resource of the channel.The two-stage spread spectrum and two-stage frequency hopping were used to the TSM-MA for reducing the complexity of receiver.Simula-tion results showed that TSM-MA has obvious advantages in bit error rate(BER) performance over time frequency code multiple access(TF-MA) about 3 dB and lower complexity than that of TF-MA.…”
