Problems solved by technology

[0005] Based on the above analysis, comparing the similarities and differences between the two technologies, it can be seen that the main obstacle to the coexistence of MIMO and smart antenna technology is the antenna structure: smart antennas require that the antenna spacing be 1 / 2 the signal wavelength; Spacing should be as large as possible and only used for MIMO systems

Abstract

The invention discloses an antenna array as well as a communication system and a communication method based on the antenna array. The antenna array comprises two antenna array groups, wherein each antenna array group comprises three antenna arrays in an equilateral triangle positional relation, and space among the antenna arrays is less than one signal wavelength; and each antenna array in the two antenna array groups is polarized in a dual polarization manner, the antenna arrays in the same antenna array group are polarized in the same polarization manner, and the antenna arrays in different antenna array groups are polarized in an orthogonal polarization manner. By adopting the technical scheme provide by the invention, an MIMO (multiple input multiple output) technique and a smart antenna technique can be supported at the same time, and thus data transmission utilization ratio and system capacity of the communication system are improved.

Description

technical field [0001] The present invention relates to the technical field of communication, and in particular to an antenna array, a communication system and a communication method based on the antenna array. Background technique [0002] Existing smart antenna arrays are mainly divided into omnidirectional smart antenna arrays and directional smart antenna arrays. Directional smart antennas are widely used because of their advantages such as large single-array gain, sharper service beams, and easier sector-based networking. Applications. At the same time, in order to obtain a better shaping effect and try to ensure the correlation of the signals between the antenna elements, the distance between the antenna elements is generally controlled at about 1 / 2 the wavelength of the transmitted signal. [0003] The MIMO (Multiple-Input Multiple-Out-put) technology is a key technology of the Long-Term Evolution (LTE) and the backward system. By using independent spatial channels, ...
