Embodiment Construction
[0035] The technical solution of the present invention will be further described below in conjunction with the accompanying drawings. It should be understood that the embodiments provided below are only intended to disclose the present invention in detail and completely, and fully convey the technical concept of the present invention to those skilled in the art. The present invention can also be implemented in many different forms, and does not Limited to the embodiments described herein. The terms used in the exemplary embodiments shown in the drawings do not limit the present invention.
[0036] The present invention is applicable to a point-to-point MIMO closed-loop transmission system, wherein both the sending end and the receiving end are equipped with multiple antennas, and the system has a feedback link to feed back channel information at the next moment (time period). The input-output relationship of the MIMO system can be expressed as:
[0037] y(t)=H(t)W(t)x(t)+n(t...
