— In this paper, we investigate resource allocation for a multi-user OFDMA cooperative system. Aiming at minimizing the total transmission power under target rate constraints for...
—This paper presents a SEPIC PFC converter for driving multiple lighting LED lamps. With the aid of this converter, high power factor and high efficiency can be achieved by a sim...
—In this paper, we manage to prove the log-concavity of the generalized Marcum Q-function Qν (a, b) with respect to its order ν on [1, ∞). The proof relies on a powerful math...
—This paper considers distributed protocol design for joint sub-carrier, transmission scheduling and power management in uplink/downlink multi-cellular OFDMA wireless networks. T...
The present paper deals with dynamic resource management based on quantized channel state information (CSI) for multi-carrier cognitive radio networks comprising primary and secon...
