Interference mitigation for satellite-terrestrial heterogeneous coexistence cognitive MIMO system based on DBF
Published 2014-10-01“…For the coexistence and increasing interference of satellite-terrestrial network and terrestrial wireless network,a typical scenario where the geostationary earth orbit (GEO) satellite-terrestrial network and the 4G mobile communication network coexist heterogeneously was analyzed.Besides,a multi-user cognitive system model that secondary satellite terminals interfere the primary multiple input multiple output (MIMO) 4G based stations was also proposed,with whose general signal processing was deduced.Meanwhile,digital beam forming (DBF) technology in 4G based station system was adopted to minimize the cognitive interference caused by multi-antennas and multi-users.And an optimal beam weight based on fixed azimuth interference (OBW-FAI) was proposed.Weight vector was only related to the azimuth of the interferences,thus the proposed algorithm does not need real-time and repeat calculations,and had small complexity.Finally,the numerical simulation results verify that the proposed system and algorithm can effectively reduce interference between satellite-terrestrial network and terrestrial wireless network to a certain extent.…”

Performance analysis of massive MIMO uplink with channel aging in high-speed mobile scenario
Published 2017-07-01“…Achievable sum rate was investigated for the massive multiple input multiple output (MIMO) uplink system with channel aging in the high-speed mobile scenario,and the effect of both channel aging and the Ricean factor on the power scaling law was characterized.Theoretical analysis and simulation results show that the transmit power of each user is scaled down by 1/M for the time varying Rican fading channel indicating that the Ricean factor affects the power scaling law and sum rate,and achievable channel aging only leads to a reduction of the sum rate.Moreover,the effect of channel aging on the sum rate can be ignored compared with that of the Ricean factor in the time varying Ricean fading channel.…”
