Utilization of distributed antennas provides an additional dimension for performance enhancement in 4G and beyond cellular networks. Intelligent remote antenna allocation and practical transmission scheme are two most important aspects for the design of DAS. In this study, a sectorized distributed antenna structure is introduced and correspondingly, power adjusted beam switching as a practical transmission...
We present a novel solution to the problem of handover between two different wireless technologies. We illustrate this solution with the example of LTE (Long Term Evolution) to CDMA (Code Division Multiple Access) handover. Current inter-technology handover can take approximately 6 to 7 seconds and hence can heavily impact the network performance. We assume that two receivers (primary and secondary)...
A new capacitor clamped sustainer is proposed to maintain sustain voltage stably and to reduce the cost and power consumption of PDP TV, which employs address-and-display-period-separated driving scheme. The proposed sustainer can reduce the number of components compared with the prior approaches. It also improves the energy recovery efficiency about 6%. The operational principle with its features...
