In this study, the authors investigate the hybrid decode-amplify-forward (HDAF) relaying protocol for the multiple parallel relays over independent and non-identical distribution flat Rayleigh fading channels using maximum ratio combining at the destination. They derive closed-form tight bounds for the outage probability and bit error rate (BER) of the HDAF(More)
We present a method for exactly solving the optimization problem for a scenario of discrete rate adaptive modulation. The aim is to maximize the spectral efficiency based on the imperfect channel estimation condition, constant power and average bit error rate(BER) constraints for multilevel quadrature amplitude modulation MQAM over Rayleigh flat fading(More)
Biologic agar-block method was developed that allowed wood samples to be evaluated and monitored in terms of colonization and development of the decay by Basidiomycetes fungi (Coriolus versicolor) and to be directly classified based on mean mass loss. In this research, the in vitro decay of five commercial woods by Coriolus versicolor was studied by the(More)
