"reflection-type polarization-independent phase-controllable anisotropic STCM... converted two baseband signals into linearly time-varying control voltage sequences with different slopes, respectively, and applied them to two polarization channels of anisotropic STCM... improves channel capacity and space utilization by using space-frequency-polarization-division multiplexing, which provides low-cost and high-integration scheme for constructing multiple-user collaborative wireless communication networks"
