Iterative Receivers for Downlink MIMO-SCMA: Message Passing and Distributed Cooperative Detection
The rapid development of the mobile communications requires ever higher spectral efficiency. The non-orthogonal multiple access (NOMA) has emerged as a promising technology to further increase the access efficiency of wireless networks. Amongst several NOMA schemes, the sparse code multiple access (SCMA) has been shown to be able to achieve better performance. In this paper, we consider a downl...
متن کاملDistributed Iterative Detection Based on Reduced Message Passing for Networked MIMO Cellular Systems
This paper considers base station cooperation (BSC) strategies for the uplink of a multi-user multi-cell high frequency reuse scenario where distributed iterative detection (DID) schemes with soft/hard interference cancellation algorithms are studied. The conventional distributed detection scheme exchanges soft symbol estimates with all cooperating BSs. Since a large amount of information needs...
متن کاملDetection algorithms and ASIC designs for MIMO-OFDM downlink receivers
Future wireless systems will require high data rate with low transmit and processing power consumption. A combination of multiple-input multiple-output (MIMO) transmission with orthogonal frequency division multiplexing (OFDM) is a promising approach for offering better performance in terms of the capacity and quality of service (QoS). The detector in the wireless receiver is one of the highest...
متن کاملIterative Detection and Decoding for MIMO Systems with Knowledge-Aided Message Passing Algorithms
In this paper, we consider the problem of iterative detection and decoding (IDD) for multi-antenna systems using low-density parity-check (LDPC) codes. The proposed IDD system consists of a soft-input soft-output parallel interference (PIC) cancellation scheme with linear minimum mean-square error (MMSE) receive filters and two novel belief propagation (BP) decoding algorithms. The proposed BP ...
متن کاملIterative receivers for coded MIMO signaling
In this tutorial paper we describe iterative receivers that combine a soft decoder for a general space–time code with a spatialinterference canceler. The performance of these receivers is analyzed by using EXIT charts, a convenient graphical description that yields quite accurate results. By properly combining the EXIT characteristics of the canceler and of the decoder, the convergence behavior...
