In this paper we study the effect of the channel estimation error on the performance of successive group decoding (SGD) schemes. The contribution of this paper is to evaluate the performance of such systems in the interference MIMO channel environment. Precisely, we aim to assess the sensitivity of such decoding techniques to the imperfect estimation of the channel state information (CSI). The system...
Because of the crucial importance of the group decoding techniques to achieve higher data rates, and also since the massive MIMO expected to be a promising key 5G wireless technology, we aim in this paper to consider the problem of formulating the achieved capacity of the massive MIMO optimal successive group decoding (OSGD) system. To the best of the authors knowledge there is neither exact nor approximate...
In this paper we aim to assess the performance of the optimal successive group decoder (OSGD) in the wireless interference channel (IC) for different scenarios using wide range of testing metrics. Therefore, we inspect the capability of OSGDto mitigate interference, also, we evaluate its minimum required energy per bit under specific quality of service (QoS) constraints. This paper explores the performance...
This paper investigates performance of the constrained partial group decoding (CPGD) technique in interference channel (IC) environment. It demonstrates the CPGD capability to manage and mitigate interference comparing with other interference mitigation schemes which are based on interference alignment strategy; this comparison is carried out for MIMO interference channel. Numerical results show that...
In this study, the authors propose a transceiver system for large-scale multiple-input??multiple-output (MIMO) (LSM) wireless communications. The authors present the main challenges facing such LSM system, also, they find solutions for those problems. The transmitters in this proposed downlink system uses a simple fair user scheduling based on limited-feedback algorithm with basic random precodeing...
