Abstract

Relaying is one of the latest technologies developed for next generation wireless networks. The purpose of relays in these networks is to increase the coverage and bitrates for cell edge users. Thus they are considered for Next generation wireless communication systems like Wi-Max (IEEE 802.16m), 3GPP LTE-Advanced (4G) and 5th Generation wireless networks to provide considerable increase in data throughput than the previous wireless communication systems. Reduction in deployment cost and easy to utilize are other promising features of these technologies. The objective of this paper is to understand the existing relay techniques, both cooperative and non-cooperative and outline the advantages of Relay implementation. Reduction in transmission power requirement for Simple Relay is shown in comparison with the conventional direct transmission, using Matlab simulation. Also SER (Symbol error rate) is calculated at the receiver for no relay and relay scenario (Amplify & Forward Relay) using Matlab to show the improvement using Relay node. Finally the benefits of Cooperative relaying is outlined using Matlab simulation.

下一代无线通信网络用中继的性能评价

中继是为下一代无线网络发展的最新技术之一。这些网络中中继的目的是增加蜂窝边缘用户的覆盖范围和比特率。因此，它们被考虑用于下一代无线通信系统，如Wi-Max (IEEE 802.16m)， 3GPP LTE-Advanced (4G)和第五代无线网络，以提供比以前的无线通信系统显著增加的数据吞吐量。降低部署成本和易于使用是这些技术的其他有前途的特点。本文的目的是了解现有的中继技术，包括合作和非合作，并概述中继实现的优势。通过Matlab仿真，对比了简单继电器与传统直接传输相比，降低了传输功率要求。此外，使用Matlab在无继电器和继电器场景(放大和转发继电器)的接收器上计算SER(符号错误率)，以显示使用继电器节点的改进。最后通过Matlab仿真概述了协同继电保护的优点。
