چکیده
The WiMAX (Worldwide Interoperability for Microwaves Access) is a broadband wireless data communication technology based around the IEEE 802.16 standard providing high-speed data communication over a wide area along with cost effective access. MIMO-OFDM technology is a combination of multiple-input multipleoutput (MIMO) wireless technology with orthogonal frequency division multiplexing (OFDM) that has been recognized as one of the most promising techniques to support high data rate and high performance in different channel conditions. Alamouti’s space time block coding scheme for MIMO system has drawn much attention in wireless technologies just because of its decoding simplicity.

A Parallel multiplier using approximate compressors are proposed in this paper. The two new approximate 4-2 compressors are proposes that the simplified compressors have better power consumption than the optimized 4-2 compressor existing designs. These approximate compressors are then used in the restoration module of a Parallel multiplier. Four different schemes for utilizing the proposed appr...

several edge recognition strategies have now been planned within the past decades. Many are derived from differential strategies such as for example Sobel, Roberts, Laplacian operators, and therefore on. Nevertheless these calculations are quite sensitive to sound, in order to restrain sound before sensing edges. In this report intensive literature review has been presented in numerous edge rec...

This paper describes the cross-talk analysis of high-speed PCB design. Some models using multiple PCB traces above a ground plane having guard traces and vias are taken and the results are obtained from modeling and simulation using Ansoft HFSS software tool and are compared with the experimental results. Reduction techniques of crosstalk are highlighted.
