A novel distributed space-time block code (STBC) for the next generation mobile TV broadcasting is proposed. The new code provides efficient performance within a wide range of power imbalance showing strong adaptivity to the single frequency network (SFN) broadcasting deployments. The new code outperforms existing STBCs with equivalent decoding complexity and approaches those with much higher c...

It is very troublesome that repeaters could interfere with one another. So we need to coordinate them. In our paper, we flexibly use the technology CTCSS (Continuous Tone-coded Squelch System) to avoid interfere and accommodate more simultaneous users with the least repeaters. Then we propose a mixed-frequency-band repeater network consist of some single-frequency-point repeater networks. Secon...

It is well-known that the throughput of wireless mesh networks without frequency re-use decreases as O(1/N), where N is the number of nodes in the network. In this paper we build on this result and obtain expressions for calculating the throughput in IEEE 802.11-based mesh networks without interference. Both expressions for single-frequency and multifrequency mesh networks are obtained. We comp...

A stochastic flow network (SFN) is more suitable than a general network to describe some real systems as it is composed of multistate links as well as multistate nodes. As the nodes and the links have different capacities at different time, the minimum transmission time through a stochastic flow network is not fixed. In order to shorten the transmission time, in this paper the data are allowed ...

In single frequency network (SFN) positioning, base station (BS) identification is inevitable and non-line-of-sight (NLOS) propagation is usually dominant especially for indoor scenarios. BS identification and NLOSmitigation are two challenging problems which have significant impact on the SFN positioning performance. In this paper, a mobile tracking scheme is proposed to deal with these challe...

This paper proposes a Flexible Power Electronic Transformer (FPET) for the application in the micro-grids. The low frequency transformer is usually used at the Point of Common Coupling (PCC) to connect the low voltage grid and utility network to each other. The conventional 50Hz transformer results in enhanced low voltage-grid power management system during grid-connected operation. In this pap...
