Abstract:In multi-beam satellite systems, users suffer from 3dB power attenuation in beam-edge area. Joint transceiving can be used to improve this situation. It requires signals of several beams (downlink) or several users (uplink) to be equal-phase, which needs channel estimation and seems to be complex. The purpose of this paper is to reduce complexity of joint transceiving by compositing quasi-equal-phase beams. Firstly, radiation pattern of original component beams are discussed and calculated. Then a modified Lea… Show more
