    Improved method of compensating non-reciprocal interference in adaptive TDD MIMO-OFDM systems by ZENG Duan-yang1, SONG Rong-fang1

    Published 2009-01-01
    “…In a time division duplex(TDD) system,the channel state information could be easily obtained at the trans-mitter side without feedback due to channel reciprocity and it could be used to increase dramatically the spectral effi-ciency of a multi-input multi-output(MIMO) system.However,the interference structure between transmission directions did not necessarily correlate at all.In such a case,the downlink modulation/coding parameters based on the uplink meas-urements might lead to excessively high frame error rates(FER).Therefore,a simple closed-loop feedback method of in-terference adaptation was proposed,which made the transmit-side estimated interference be able to track the instantane-ous receive-side interference dynamically,and its performance in adaptive TDD MIMO-OFDM systems with HARQ was studied.Simulation results show that the tracking performance is well and the target FER requirement can be guaranteed.…”

    Gradient descent Sarsa(?)algorithm based on the adaptive potential function shaping reward mechanism by Fei XIAO, Quan LIU, Qi-ming FU, Hong-kun SUN, Long GAO

    Published 2013-01-01
    “…In the reinforcement leaning tasks with continuous state spaces,the algorithms are usually facing the problems of ill initial performance and low convergence speed.In order to solve these problems,the potential function shaping reward mechanism was proposed to improve the reinforcement learning algorithms.This mechanism propagates model knowledge to the learner adaptively in the form of the additional reward signal,so that the initial performance and convergence speed could be improved effectively.In view of the good performance and existing problems of the radial basis function (RBF) network,the adaptive normalized RBF (ANRBF) network was put forward to use as a potential function to generate the shaping rewards.A gradient descent (GD)algorithm named ANRBF-GD-Sarsa(?) …”
