Double search algorithm of user group selection for multiuser MIMO downlink transmission |
摘要 |
A method and system for a double search algorithm of user group selection for multiuser MIMO downlink transmission are provided. The use of optimal brute-force user group selection may require high computational expense. A first search operation may be based on a first user having a channel gain greater than that of other users, while a second search operation may be based on a second user having a channel gain greater than that of the remaining users. A maximized system capacity may be determined based on the maximized system capacities determined in the first and second search loop. A receiver pair associated with the maximized system capacity may be selected as the user group. The double search algorithm may reduce the computational complexity while achieving performances that may exceed the TDMA scheme and be similar to that of systems with ideal CSI at the transmitter. |
