Beamforming technique to reduce Interference in Relay Broadcast Channel
نویسنده
چکیده
We investigate a multiple input multiple output (MIMO) relay broadcast channel (RBC) with full cooperation between users. A beamforming and combining design is proposed based on singular value decomposition (SVD) of the channel matrix between users. Then, users can simultaneously relay each other’s information on the same frequency band with zero interference from each antenna’s transmit signal on its received signal. At the transmitter side we applied zeroforcing algorithm. For the second time slot transmission we use SVD to reduce interference between users.

In this paper, a more realistic cognitive radio network is proposed which considers several secondary links, some secondary relays, and one primary link. In the network, there are two steps of transmission from secondary sources to secondary destinations. At the first step, when primary link is idle, all of the secondary sources simultaneously broadcast their information to the relays. At the s...
متن کاملRelay-Aided MIMO Cellular Networks Using Opposite Directional Interference Alignment
In this paper, we propose an interference alignment (IA) scheme for the multiple-input multipleoutput (MIMO) uplink cellular network with the help of a relay which operates in half-duplex mode. The proposed scheme only requires global channel state information (CSI) knowledge at the relay, with no transmitter beamforming and time extension at the user equipment (UE), which differs from conventi...

In this paper, we study the emergence of topological interference alignment and the characterizing features of a multi-user broadcast interference relay channel. We propose an alternative transmission strategy named the relay space-time interference alignment (R-STIA) technique, in which a K -user multiple-input-multiple-output (MIMO) interference channel has massive antennas at the transmitter...

This paper proposes a new smart antenna beamforming scheme based on electronically steerable parasitic array radiator (ESPAR). The proposed method is capable of providing better capacity compared to the conventional ESPAR. The termination of each antenna element in this structure comprises a PIN diode in addition to a varactor. Using PIN diode besides the varactor provides more degrees of freed...
متن کاملBeamforming-Based Physical Layer Network Coding for Non-Regenerative Multi-Way Relaying
We propose non-regenerative multi-way relaying where a half-duplex multi-antenna relay station (RS) assists multiple singleantenna nodes to communicate with each other. The required number of communication phases is equal to the number of the nodes, N. There are only one multiple-access phase, where the nodes transmit simultaneously to the RS, and N − 1 broadcast (BC) phases. Two transmission m...
