Phase Shift Keying, quadrature phase shift keying), 16QAM (Quadrature Amplitude Modulation, orthogonal width
Degree modulation) etc. need the modulation system of relatively low SNR (SIGNAL-NOISE RATIO, signal-to-noise ratio)) carry out closed-loop control channel
Link setup, after link setup, the phase angle and the error estimation of desired angle that can receive opposite end come out that (specific algorithm can be with
Using existing arbitrary error estimation algorithm, details are not described herein), the index that can be observed includes MSE (Mean Square
Error) and FEC (Forward Error Correction) decoding cases, pass through the closed-loop control channel having built up, send
To local terminal, after local terminal receives, according to the distribution situation of error, the phase actual conditions of opposite end receiver are calculated, with ideal
It is required that 90 ° of phase relations compared after, it is possible to by way of issuing particular phases regulation and control instruction, inform to local terminal
Phased array antenna control module carry out corresponding array element group and carry out phase shift angle having adjusted, due to the use of in Fig. 8
Circuit structure, all phase adjusteds are all automatically controlled adjustable, and phase shift relationship can be corresponding with the realization of specific circuit
Get up, during adjusting, the mode of stepping may be used, after treating that opposite end updates its receiver MIMO performance indicators again,
It is adjusted again, if the performance indicator of opposite end feedback has reached in certain threshold range, that is, stops adjusting, it is believed that should
The closed loop phase adjustment process of mimo system finishes.Since transceiver channel is reciprocity, after local terminal is adjusted, acquiescence
The link of opposite end to local terminal is also completed with regard to adjusting, and LoS mimo systems enter the state of long-term stable operation.

Two horizonally-polarized array row 20, the polarized antenna arrays 21 answered) receive power P rx (x optional V0, H0, V1, H1)；
S1203：Judge whether Ptx-Ld-Prx is less than or equal to difference power threshold value, if so, going to S1205；Otherwise, it goes to
S1204；
S1204：To Ptx, the main lobe angle of radiation of corresponding polarized antenna arrays is adjusted, until Ptx-Ld-Prx is small
In equal to difference power threshold value；Go to S1205；
