Abstract

The invention discloses an antenna selection method based on a GA (Genetic Algorithm). Aiming at the defects that the complex rates of the combined capacities of all antennae calculated by a maximum capacity algorithm are tend to exponential growth, a suboptimum, even optimal transmitting and receiving antenna with maximum capacity can be quickly searched by adapting genetic searching to join multi-antenna transmission, therefore the complexity and calculated amount of the antenna selection can be reduced, and the complex rate can be linearly increased only when the number of the antennae is increased, therefore the calculated quantity and calculating time length can be greatly reduced.

Description

technical field [0001] The invention relates to the technical field of mobile communication, in particular to a genetic algorithm-based antenna selection method. Background technique [0002] At present, in a multi-antenna wireless communication system, multiple antennas are deployed on the transceiver node to increase the transmission rate and resist channel effects such as multipath. However, due to the relatively expensive radio frequency circuits, it is impractical and unnecessary to assemble a radio frequency link for each antenna. Usually, some optimal antennas are selected for transmission by using the established antenna selection criteria to reduce system costs and ensure higher transmission rates. Purpose. [0003] Currently, antenna selection criteria are based on algorithms such as maximum capacity and maximum signal-to-noise ratio. The algorithm based on the maximum capacity can select the optimal combination of transmitting and receiving antennas, but it need...
