A simple closed-form expression is provided for the coverage probability of cellular systems under Hoyt (Nakagami-q) fading, which models fading scenarios more severe than Rayleigh. The accuracy of the proposed framework is validated through Monte Carlo simulations.
In this paper, a joint adaptive modulation and multiple-input multiple-output (MIMO) transmission scheme is considered. An efficient use of radio resources shall be based on channel state information at the transmitter (CSIT) to adjust the modulation order and MIMO transmission mode. A new suboptimal algorithm is proposed for link adaptation in a MIMO-OFDMA cellular system under spatially correlated...
Despite commercial 3G networks are starting to be fully operational and high speed data packet access (HSDPA) is on its way to be deployed, operators and manufacturers are already in a race towards 4G technologies. The road to 4G has a mandatory milestone in long term evolution (LTE) as it is a promising technology which will allow backwards compatibility besides a higher performance. Thus operators,...
