It is a useful tool for designing waveguide slots array antennas, including the linear array and the planar one. This software is developped by Gatti. But it is a demo version, you can get the perfect one form its website. Good luck! SWAN DEMO Setu

Alamouti Code to achieve diversity without channel knowledg at the transmitter It is assumed that system contains 2 transmit antennas and one receive antenna. At the transmitter the data of a two consecutive slots will be considered. At the odd time

提出两种基于盲源分离方法的标签防碰撞算法，解决标签密集的多天线RFID 系统中的标签碰撞问题。在一个确定的 时隙内， 当发射反向反馈信号的标签数目不超过阅读器天线的数目时， 这些标签可以通过盲源分离算法被阅读器成功识 别；信号，直到所有标签被成功识别出来。仿真结果表明，新算法能使得RFID 系统获得更加高效的吞吐率，能比基于ALOHA 的标签防碰撞算法具有更小的时耗，尤其是当标签数目较大时更加显著。-two tag anti－collision algorithms based on
