| Abstract: | Aiming at the high hardware cost brought by multiple antenna that needs multiple RF chains, this paper analyzes the necessity for MIMO antenna subset selection with low complexity, and introduces the increasing antenna selection algorithm, decreasing antenna selection algorithm, and improved increasing and decreasing antenna selection algorithm. Simulation results show that increasing and decreasing algorithm can quickly select the antenna subset that makes the biggest system capability. This algorithm is simple and available, and the simulation result is very close to the result by exhaustive search method. |
