Transceiver Decoupling of Multivariate Symmetric Hybrid Precoding Based on 5G
Algorithm 1
The fast beam search model based on GMCS in the LoS scenario.
Input: ,. The initial search interval of the transceiver is ,
1. if ( is a positive integer) do
2. for do
3. The transmitter transmits training beams 1 and 2 in sequence according to 2-GMCS in the corresponding interval. The receiver adopts the quasi-omnidirectional mode to receive in the interval. The receiver compares the received power with the threshold to find the stage and feeds it back to the transmitter, and the transmitter updates the search interval of the next stage
4. The transmitter transmits the same training beam twice along the direction, and the receiver uses training beams 1 and 2 to receive within the range of . The receiver finds the optimal receiving beam number at this stage by comparing the received power with the threshold and updates it to the search interval of the next stage
5. end for
6. else
7. Perform Step 3 and Step 4 times in sequence, and the output is marked as ,
8. The transmitter transmits training beams 1, 2, and 3 in sequence according to 3-GMCS in the corresponding interval. The receiver adopts the quasi-omnidirectional mode to receive in the range. Meanwhile, the receiver finds this stage by comparing the received power with the threshold and feeds it back to the transmitter. The corresponding search interval is
9. The transmitter transmits the same training beam three times along the direction, and the receiver uses training beams 1, 2, and 3 to receive within the range of . The receiver finds the optimal receiving beam number at this stage by comparing the received power with the threshold and completes the search
