    Performance analysis of weighted non-coherent receiver for UWB-PPM signal in multipath channels by WU Jian-jun, LIANG Qing-lin, XIANG Hai-ge

    Published 2006-01-01
    “…The BER performance expressions and weighting coefficients of the weighted non-coherent receiver for the UWB-PPM signal were analytically derived.Subsequently,the analytical results were validated via Monte-Carlo simula-tion,and the impacts of the sub-interval width and the timing error were also numerical analyzed.It is illustrated that the weighted receiver is at least 3dB superior to the conventional non-coherent receiver,and is robust to the variations of sub-integration width and the timing error.…”

    Coordinated beamforming algorithm assisted by receive beamforming vector estimation by Ying HUANG, Gang-ming LV, Shi-hua ZHU

    Published 2014-02-01
    “…By sharing a small amount of information among cooperated base stations(BSs), the proposed algorithm estimates the receive vectors of related users at the BSs based on MVDR criterion, which are then utilized to optimize the design of transmit beamforming vectors. The simula-tion results and analysis show that the proposed distributed scheme can achieve the performance close to that in the cen-tralized scheme with lower overhead and complexity. …”

    Pilot based channel estimation in amplify-and-forward MIMO relay networks by Jian ZHOU, Bao-yu ZHENG

    Published 2014-09-01
    “…A channel estimation method in two time slots for two-hop amplify-and-forward MIMO relay channels is pro-posed.An algorithm for computing the optimal pair of source pilot and relay amplify matrix is developed,which mini-mizes the mean square error of the source-to-relay channel estimation subject to both power constraints at the source and the relay.The signal matrices are decomposed into unitary components and diagonal components.Then the bisection method is used to obtain the optimal diagonal components of the source pilot and the relay amplified matrix.The simula-tion results show that the proposed method has no ambiguity in the channel estimates.The effects of the channel correla-tion and the number of antennas on the performance of channel estimation are also analyed.…”
