In this paper, we study the problem of joint resource allocation in the two-way relay system, where a pair of multi-antenna users wish to exchange information via a multi-antenna amplify-and-forward relay under orthogonal frequency-division multiplexing (OFDM) modulation. We formulate a sum-rate maximization problem subject to a limited power constraint for each individual user and relay. Our resource...
Joint transmission (JT) allows base stations (BSs) to serve multiple users (UEs) in the same time and frequency resources, wherefore inter-user interference (IUI) will arise. To solve this problem, an inter-user interference suppressed precoding (IUISP) scheme is proposed in this paper. IUISP contains two steps: firstly, we utilize the system degree of freedom to suppress interference generated by...
Traditional detection algorithms for frequency selective Orthogonal Frequency Division Multiplexing Vertical-Bell Labs Layered Space-Time system (OFDM-V-BLAST) suffer from high computational complexity. So it's necessary to develop a detection algorithm to minimize the computational complexity and improve BER performance. This paper presents a new reduced-rank detection algorithm based on MMSE Sorted...
Traditional equalization algorithms for multiple input multiple output (MIMO) systems suffer from high complexity and low convergence rate. So it's necessary to develop an equalization algorithm to minimize the computational complexity and improve the convergence rate. This paper presents a new adaptive reduced-rank linear equalization algorithm, called rectangle unitary multistage Wiener filter reduced-rank...
