摘要: Enabling ultra fast systems has been widely investigated during recent decades. Although polarization deployed from the beginning in satellite communications, nowadays it is being exploited to increase throughput of links. More precisely, application diversity techniques domain may provide reliable, robust, and communications. Better more flexible spectrum use also possible if transmission reception can take place simultaneously close or even overlapping frequency bands. In this paper we investigate novel signal processing communications fixed mobile scenarios. First, four-dimensional (4D) constellations for forward link. Second, focus on scenario introduce an adaptive algorithm which selects optimal tuple modulation order, coding rate, MIMO scheme that maximizes constraint a maximum packet error rate. Finally, describe operation radio transceivers cancel actively self-interference posed by transmit when operating full-duplex mode.
