Abstract

For channel estimation technology of multiple antenna communication system based on cognitive radio architecture, traditional zero correlation zone sequences (which assume the availability of the entire spectral band) can not be used because their orthogonality will be destroyed by the spectrum hole constraint. This paper introduces the channel estimation algorithm in multiple antenna communication system and points out the requirement of the ideal sequence set, then on complex electromagnetic environment, i.e., under the condition of the existence of spectrum holes, joints optimization evaluation indexes of limited spectrum and good cycle correlation degree, designs a suitable sequence set, which can be applied to the channel estimation algorithm of cognitive radio system. The simulation results verify the effectiveness of the new sequence set.

Key words： Multiple antenna channel estimation Complex electromagnetic environment Limited spectrum Sequence design
