Discrete particle cluster algorithm based V-BLAST system detecting method

Abstract

The invention discloses a V-BLAST system detection method based on discrete particle swarm algorithm, which belongs to the technical filed of artificial intelligence and aims to overcome the disadvantages in the prior art, such as high calculation complexity and code error rate. The inventive method can provide better performance of code error rate and reduce the actual complexity. The method is implemented by the steps: 1. initializing a particle swarm with a size of m, randomly generating a position vector of each particle, the dimensional number of the position vector being the same as the transmitting antenna, wherein the setup variation rate is m, the evolution algebra t is zero and the condition of ending the determined algorithm is that the maximal iterative algebra is ga; 2. calculating the particle adaptability, judging whether the particle adaptability meets the condition of iterative termination, if meeting the condition, the algorithm is ended, otherwise going to the step 3; step 3, updating the particle position, executing the variation operation, updating the individual extreme value and the overall extreme value, and going to the step 2. The invention can be used to solve the detection problem of vertical layered space-time system in the field of wireless communication.
