Research on the Scheme and Performance of Linear SA for Beam-forming
نویسنده
چکیده
Firstly, this paper researches on the scheme of amplitude weighting(AW) for smart antenna(SA) beamforming in linear array. With the proposed mathematical model in this paper, QPSK base-band AW is an effective method for linear SA to realize multi-user and multi-direction transmission, by which the perfect directional beam-forming can be realized with low complexity and low cost. Secondly, this paper analyses the performance of linear SA with 6 array elements(AEs) in different application scenarios. Compared with carrier phase-shifting, the implementation scheme of beam-forming by AW has the feature of easy to implement and high reliability, so that the popularization and application of SA is possible. Keywords-smart antenna (SA); beam-forming; amplitude weighting (AW); QPSK;6 array elements(AEs)

A novel method for laser forming of two-step bending of a dome shaped part
In recent decades, one of the challenges in sheet metal forming was production of two-step bending surfaces without mechanical tools and external force or by a combination of heat source and mechanical tools. Forming with a heat source such as laser beam has the potential for forming arbitrary 3D shapes such as two-step bending surfaces. In this paper a novel method for laser forming of complic...
