Realization of Super Large Autostereoscopic Display Wall

The suitable lenticular lens for large panel autostereoscopic display was designed,and its optical transmission property was analyzed.The location of the best viewing zones and the relationship between screen size and the optimum viewing distance were proposed.On the basis of the original monitor,rear projection screen material suitable for large panel three-dimensional(3D) monitor and splicing method for 3D display wall were studied.Close to 150-inch-large panel stereo display wall was achieved.

Investigation of Improved Signal Process and Control Circuit for ColorPDP

We present an alternative current-plasma display panel （AC-PDP） signal process and control circuit that fulfills the signal process and transform function. We proposed a novel driving logical waveform generator based on the SCI interface, which can real-time adjust the parameters to optimize performance of the PDP and facilitate the research and test. The use of nesting state-machine and parameterized design not only improves the resource utilization, but also makes it efficient and readable. The design has been written in synthesizable Verilog and fully verified using Xilinx FPGA device and applied in 42 - in AC- PDP module.     

Power-Effective in the Cell Sectorization Using Wide-Beam and Narrow-Beam for Multi-hop Relay Network

Multi-hop relay is a significant topic in the wireless communication and it is provisioned in the 802.16j standards.At present,the major research on multi-hop relay is focused on the capacity,coverage,coordination,throughput,etc.But in this paper,a new concept about power-effective was discussed.Then,two power-effective coverage extension methods using two sectorized cellular approaches were introduced,i.e.,the widebeam three sector cell(WBTC) and the narrow-beam three sector cell(NBTC).Under such topologie...     

Design and Implementation of DSP—Based IEEE802.16a OFDM System

A set of integrated Orthogonal Frequency Division Multiplexing (OFDM) modulation and demodulation system is proposed and its performance is verified in reference to the standard of IEEE802.16a for WMAN. The design, combined with analogy front-end, adopts Texas Instrument ( TI ) Company's 6701 evaluation module (EVM) to construct digital Intermediate Frequency (IF) platform. A DSP-based baseband processing software module is embedded into the system. The proposed scheme makes it possible for users to select various software modules to set up corrections with different throughput performance. Taking into account the given hardware configuration, the design aims to optimize the algorithm modules to accomplish better system performance.     

HARQ Scheme for MIMO Systems with Antenna Selection

A new type hybrid automatic repeat request(HARQ) scheme based on orthogonal space-time block code(OSTBC) is proposed and evaluated in multiple-input multiple-output(MIMO) systems.The transmit antennas are selected based on the feedback from the receiver.The modulated symbols are encoded by spacetime block code(STBC) and obtained by space time code blocks which are suitable for the number of selected antennas.The total packet error rate(PER) is given by defining the decoding function and the best value of th...
