Transceiver Decoupling of Multivariate Symmetric Hybrid Precoding Based on 5G

Algorithm 2

The paper swarm hybrid precoding algorithm [33].

Input: , , , the initial search interval of the transceiver

Output: ,

1. Begin

2. The value of is determined according to , and a codebook based on () score search is designed

3. The transceiver searches through all codebook combinations, and the receiver records the corresponding power. Through searches, it is determined that the region of the strongest path corresponding to the transceiver is and

4. Algorithm 1 is executed to find and

5. End
