Abstract：This paper presents a NON-coherent Antenna Selection (NON-AS) algorithm for multi-antenna transmission system. The combination of Generalized Likelihood Ratio Test (GLRT) and Antenna Selection (AS) is applied to Unitary (U)signal transmission system, and antenna selection and signal detection do not require Channel State Information (CSI). Therefore, the NON-AS algorithm, compared with coherent antenna selection, can greatly reduce system complexity. This paper only discusses the selection of receiving antenna. Selection criterion is based on the Frobenius-2 norm of received signal vector at each receiving antenna. Simulation results indicate that under the condition of high Signal to Noise Ratio (SNR), by selecting a set of receiving antennas which observe the largest Frobenius-2 norm of received signal vector, the same diversity gain as the one obtained by using all the receiving antennas can be achieved.
