—The channel capacity of a multiple-input–multiple-output (MIMO) communication system depends substantially on correlation between individual receive branches. In this letter, we investigate the MIMO capacity using the correlation matrix approach and the Salz–Winters spatial correlation model. It is shown that for a linear array, correlation has no impact(More)
Recent studies conclude that patient survival during a health emergency situation depends on the effective pre-hospital healthcare. Mobile telemedicine exploits different wireless network technologies in order to tackle this problem. This paper looks into the case of mobile telemedicine service provision in a moving vehicle (ambulance). The special(More)
—Scope of this paper is to analyse four subcarrier allocation algorithms for multicellular OFDMA networks, namely coordinated, sequential, random and an innovative technique of cell splitting, that uses both random and coordinated subcarrier allocation. Common characteristic of these subcarrier allocation algorithms is that they do not require knowledge of(More)
The issue of fairness and throughput trade-off in UMTS WCDMA network planning is discussed in this paper. The employed radio resource management (RRM) fully supports rate adaptation and hence, new potentials arise in terms of system throughput and fairness. The authors study four low complexity RRM algorithms that perform efficient rate adaptation in order(More)
