A Joint Real Grassmannian Quantization Strategyfor SISO IA with Limited Feedback

Abstract—Interference alignment (IA) is a scheme to achievedegrees of freedom (DOF) of interference network at high signalto-noise ratio (SNR). In order to implement IA scheme infrequency-division duplexing (FDD) system, receivers feedbackchannel state information to transmitters. Th
