Using optical signal processing to reduce electronic hardware costs for wideband beamforming with RF antenna arrays 利用光信号处理降低射频天线阵列宽带波束形成的电子硬件成本

We focus on the applications with the number of antenna elements L much greater than the number of users K, e.g. multibeam satellites. For wideband signals, beamforming requires frequency selective processing that is expensive if electronic filters are used. We investigate the use of optical signal processing to reduce the number of electronic filters from L in the base case with one filter per antenna element. We first show that wideband nulling of K -1 interfering users can be done by performing conventional beamforming in optics followed by K electronic filters. We then focus on digital transmission with K users and show that, instead of K independent symbol detections after interference nulling, joint detection allows us to perform conventional beamforming in optics followed by K electronic matched filters. The key observation is that the number of electronic filters depends on the number of users K and not on the number of antenna elements L.","PeriodicalId":137956,"journal":{"name":"2004 IEEE International Topical Meeting on Microwave Photonics (IEEE Cat.
