摘要: High speed trains are becoming a popular means of transportation all over the world, such that it is necessary to develop and deploy an infrastructure provide broadband passengers on train. However, there several challenges high communication systems including fact channel conditions change drastically hindering estimation accuracy overall system performance, which leads link failure. Cooperative relaying one novel schemes used in wireless improve throughput performance. In this paper, we propose general analytical approach evaluate performance dual-hop network with fixed relay train carriage Nakagami-m fading environment. The assumed employ either decode-and-forward (DF) or amplify-and-forward (AF) scheme. Both, destination nodes be mobile follow Random direction (RD) mobility model. Under setting, derive exact expressions for outage probability average bit error (ABEP). derived results applicable topology dimensions, conditions, digital modulation schemes. verified by Monte Carlo simulations.
