BER and SIR Based Hybrid Link Algorithms Performance in Mobile Radio Channel

Abstract

In the next generation of mobile communication networks (B3G) theusing of effective handling of radio resources is supposed (channels,power and transmission rate) with simultaneous delivery of requiredservices, in which the quality of service (QoS) is guaranteed. In thisarticle we have described and simulated new BER based, SIR-frame basedand SIR-slot based link adaptation algorithms. Algorithms were designedto increase efficiency of data transmission among user equipment andbase stations (uplink) expressed by throughput and the outageprobability for each link. Simulation results of hybrid adaptation(power and modulation BPSK, QPSK, 16-QAM, 64-QAM) are compared andexpressed as data throughput and outage probability for differentsimulation environments (pedestrian channel with mobile subscriberspeed 10 km/s and vehicular channel with speed 120 km/h).
