A new method for solving the wideband beamforming problem is proposed in this paper based on directional uniform circular *** basic idea is designing a narrowband beamforming spatial filter at a specific frequency and using the obtained filter weights directly to wideband signals,which reduces the complexities of designing and *** the premise of knowing signals’ direction information,this paper uses the method of least square with linear constraints to design the narrowband spatial *** the directional uniform circular array is insensitive to the variation of frequency,coincident beams and notches are obtained at different frequencies of the wideband signal by using the obtained narrowband spatial filter *** computation complexity of array signal processing can be greatly reduced by using the method proposed in this paper,which is convenient for real-time signal processing.

Two simple quantum broadcast communication schemes are proposed. A central party can broadcast his secret message to all the legitimate receivers simultaneously. Compared with the three schemes proposed recently （Wang et al. 2007 Chin. Phys. 16 1868）, the proposed schemes have the advantages of consuming fewer quantum and classical resources, lessening the difficulty and intensity of necessary operations, and having higher efficiency.
