Multi-Input Multi-Output Orthogonal Frequency Division Multiplexing (MIMO-OFDM) with SpaceFrequency Block Coding (SFBC) is widely used as a promising technique for next generation broadband wireless applications. As encountered for multicarrier systems, a major challenge of SFBC MIMO-OFDM transmission systems is the problem of high peak-to-average power ratio (PAPR), which leads to severe disto...

This paper reports a comparative study of burning Thai rice husk, sunflower shells and fine rubberwood sawdust as well as co-firing of the sawdust and shredded eucalyptus bark in the swirling fluidizedbed combustor (SFBC). All experiments for firing individual fuels were performed for the combustor heat input of ∼300 kWth. However, in the co-firing tests, the fuel mixture was delivered at a fix...

Wireless communication systems are already exploiting powerful multiple antenna technologies based on the principles of multiple input multiple output (MIMO) communication. By now, the principles of single user MIMO communication links are well understood. The next generation of systems, though, will use more advanced MIMO communication strategies that support multiuser MIMO. In this way, the s...

The ABL4 analyser is designed for stat determination of blood gas (pCO2, pO2), pH, potassium and haemoglobin (Hb), a panel particularly adapted to the follow-up of liver transplantation. The performance of the analyser in classical tests was evaluated; in addition, K+ measurements were performed in specific conditions (linearity in a non-physiological range, erythrocyte interference). The evalu...

In this paper, we analyzed a numerical evaluation of the performance of MIMO radio systems in the LTE network environment. Downlink physical layer of the OFDM-MIMO based radio interface is considered for system model and a theoretical analysis of the bit error rate of the two space-time codes (SFBC 2×1 and FSTD 4×2 codes are adopted by the LTE norm as a function of the signal to noise ratio. An...
