Objective audio quality of spatial audio coding systems is difficult to be measured because of the limited measurement capability under multiple channels especially at low bit rate. Conventional PEAQ tool computes the basic audio quality based on single channel signal and cannot describe the reconstruction effectiveness of the spatial information. The basic quality and the spatial effect are two major...
In this paper, we present two construction schemes for LDPC codes in coded cooperative communication. The scheme which uses rate compatible LDPC codes based on puncturing parity bits is presented first. Then the paper proposes the scheme which uses QC-LDPC codes based on the multiplicative inverses in finite fields. Detailed implementations of two schemes are presented. Simulation results show that...
Cooperative communication technology has been widely studied in recent years due to providing higher resource utilization and more reliable communication. In this work, we consider a downlink multi-user multi-input-multi-output (MU-MIMO) system with cooperative multi-cell transmission. Assuming that the channel state information are available at cell and user, we propose a simple user scheduling algorithm...
Relay communication network has been widely studied in recent years due to their ability to provide more reliable communication through enhanced diversity. In this work, we consider a downlink multiuser multi-input-multi-output (MU-MIMO) relay network under amplify and forward (AF) protocol. Coordinated relay system can provide the additional diversity gain due to adding the relay station (RS) compared...
