A communication system (10B) comprises a signal generator (112), polarizer (102), signal combiner (123), transmitter (105), positioning device (120A), and controller (50A). The signal generator (112) converts first and second received data streams (113A, 113B) into respective first and second orthogonal linearly polarized signals (118A, 118B). The polarizer (102) is at a first rotation angle and converts first and second orthogonal linearly polarized signals (118A, 118B) into, respectively, a first right-hand-circularly polarized (RHCP) signal (122A) and first left-hand circularly polarized (LHCP) signal (122B), which are combined in signal combiner (123A) into a signal sent by transmitter (106) to a receiver (108). The positioning device (120A) adjusts the first rotation angle to substantially increase isolation between third and fourth orthogonal linearly polarized signals (124A, 124B) at the receiver (108). The controller (50A) performs the real-time analysis of transmission loss and directs the positioning device (120A) to adjust the first rotation angle. |
