Qianqian Yang · Computer Knowledge and Technology · 2008
The optimal solution of MIMO signal detection is a NP problem.Making use of the properties of quantum mechanics such as quantum parallelism and entanglement,Quantum Neural network(QNN) can solve this problem efficiently.This paper adopts method of Hopfield neural network to realize MIMO signals detection.Basic on mapping between detecting sequence Maximum a posteriori Probality(MAP) optimum reception likelihood function and energy function of Hopfield nerve net,we conformat a kind of quantum neural network MIMO singal detector.Computer simulation results show that the method has powerful property in bit error rate.
