The through silicon via (TSV) technology provides a promising way to realize RF micro system. In this paper, a coaxial vertical TSV transition is presented with one TSV in center as signal conductor and six TSVs arranged in circle as ground path. The front-to-front test structure consists of two coaxial TSV transitions connected in a cascade way. As a result, the properties of the TSV transition is...
This paper investigates the optimal modified tracking performance of multi-input multi-output (MIMO) networked control systems (NCSs) with packet dropouts and bandwidth constraints. Some explicit expressions are obtained by using co-prime factorization and the spectral decomposition technique. The obtained results show that the optimal modified tracking performance is related to the intrinsic properties...
This article proposes a method of video transmission by partition based on network differentiated service. The method firstly divides videos spatially and temporally into partitions according to a significant area deciding algorithm, and then establishes QoS indexes and set the service type for different video partitions according to network available bandwidths and MPEG-4 frame types. Using different...
In this paper we present an asynchronous compressive sensing front-end for radar systems. By using a continuous-time ternary encoding scheme (CT-TE), the amplitude variations on radar pulses are converted into timing information. The oversampling architecture mitigates the quantization error and improves time-delay estimation accuracy. The high data volume resulting from oversampling is reduced by...
In this paper, a high selectivity dual-band dualmode microstrip bandpass filter (BPF) with multi-zeros is proposed utilizing short-stub-loaded folded SIRs and Y-shaped source-load coupling structure. The folded SIR supports two non-degenerated modes, thus achieving two independently controlled passbands with adjustable bandwidths by means of coupling two such SIRs. Due to the main path signal counteraction...
Carrier aggregation (CA) has been considered to meet LTE-Advanced (LTE-A) requirements of wider bandwidth up to 100 MHz and maintain backwards compatibility with LTE Release 8 (Rel-8) simultaneously. High cubic metric (CM) values and Peak-to-Average Power Ratio (PAPR) of aggregated component carriers (CCs) have appeared to be a crucial issue needing to be solved for both uplink and downlink (DL) transmission...
QoS provisioning in wireless mesh networks has been to known as a challenging issue. In a distributed scheduling based wireless mesh backhaul network, conventional connection-based QoS provision mechanism requires considerable amount of overhead for per-link QoS signaling, thus cannot support high speed real time traffic. In this paper,we propose a DiffServ-like QoS provision mechanism for IEEE 802...
As the streaming media files growing larger and larger in size, it inevitably aggravates the network congestion and user perceive latency, to settle problem lots of caching algorithms have been applied in video-on-demand (VOD)system. However, different algorithm is correspondence to an unique caching replacement policy, which limits its applications and the effects are not very satisfied, so in VOD...
A novel 1.31/1.55 mu m wavelength-division demultiplexer based on a three-core photonic crystal fiber is proposed. The fiber is composed of a large central core and two up-doped cores with different core sizes. The large core is realized by the omission of seven airholes and the insertion of a down-doped rod in the center of fiber. The effective indexes of the two small cores are index matched with...
