In this letter, a novel linear transmission strategy to design the linear precoding matrix (PM) at base station (BS) and the beamforming matrix (BM) at relay station (RS) for multipleinput multiple-output (MIMO) relaying broadcast channels with direct channel (DC) is proposed, in which a linear PM is designed at BS based on DC, and the RS utilizes the PM,(More)
In this paper, we investigate joint source precoding matrices and relay processing matrix design for multiuser multiple-input– multiple-output (MIMO) nonregenerative relay networks in the presence of the direct source–destination links. We consider both capacity and mean-square-error (MSE) criteria subject to the distributed power constraints, which are(More)
In this paper, we consider the capacity of a multicast network, where a single-antenna secondary base station (SBS) utilizes the spectrum licensed to primary users (PUs) to broadcast the same information to multiple secondary users (SUs) with a single-antenna simultaneously, when the interference received by PUs is less than a predefined threshold. Based on(More)
In this letter, we address the optimal source and relay matrices design for the multiple-input multipleoutput (MIMO) relaying broadcast channels (BC) with direct links (DLs) based on weighted sum-rate criterion. This problem is nonlinear nonconvex and its optimal solution remains open. To develop an efficient way to solve this problem, we first set up an(More)
In this paper, we present an iterative reliability-based modified majority-logic decoding algorithm for two classes of structured low-density parity-check codes. Different from the conventional modified one-step majority-logic decoding algorithms, we design a turbo-like iterative strategy to recover the performance degradation caused by the simply flipping(More)
This paper deals with joint source and relay beamforming (BF) design for an amplify-and-forward (AF) multiantenna multirelay network. Considering that the channel state information (CSI) from relays to destination is imperfect, we aim to maximize the worst case received signal-to-noise ratio (SNR). The associated optimization problem is then solved in two(More)
The design of proper precoders enables the spectral efficiency for multiple-input multiple-output relaying broadcast channels (MIMO-RBC). In this work, a general MIMO-RBC is considered with two types of users (relay users and direct users) and the base station (BS) can send information continuously to the users during two phases. We then present a(More)
In this paper, we address the robust source and relay matrices design for the multiple-input multiple-output (MIMO) relaying broadcast channels (BC) with imperfect channel state information at the transmitter (CSIT). Our objective is to maximize the minimum achievable rate among all users, which dominates the quality of service (QoS) performance of the(More)
