| Abstract: | The optimal solution for the conventional multi-user detection is a NP hard problem.Taking advantages of the properties of quantum mechanics such as quantum parallelism and entanglement can solve this problem efficiently.A multi-user detection based on quantum genetic algorithm is proposed,which integrates genetic algorithm with quantum computing theory.The computer simulation results show that the method has more powerful properties than the detector based on classical genetic algorithms and has powerful p... |
