Embodiment Construction
[0054] The application will be further described in detail below in conjunction with the accompanying drawings and embodiments.
[0055] In related technologies, the adopted pairing scheme is as follows:
[0056] Assuming a MIMO uplink system, the base station has 2 antennas, and there are 2 single-antenna users in the cell. Assuming that they have been paired successfully, the channel matrix of the 2×2 VMIMO system is as follows:
[0057]
[0058] Among them, H 1 and H 2 Respectively represent channel matrices formed by two configured users and base stations, and the two paired user channels are independent of each other. At this time, the received signal vector at the base station can be written as:
[0059]
[0060] where x 1 and x 2 Represents the transmitted signals of two paired users, and n represents Gaussian white noise.
[0061] Orthogonal pairing selects users whose channels best meet the orthogonal characteristics for pairing, and then transmits user da...
