Problems solved by technology

However, for practical application scenarios, the relative positions of the transmitter and the receiver are often not fixed, and it is not necessarily possible to obtain high channel capacity in a certain range if a large channel capacity can be obtained at a specific point.
Moreover, optimizing only for a single location often cannot guarantee the stability of channel capacity in a certain area
In addition, the rotation angle between the receiver and the transmitter will also cause large fluctuations in the channel capacity

Abstract

The invention discloses a method for optimizing the size of a four-transmitting two-receiving antenna array to obtain the maximum average channel capacity, which comprises the following steps of: establishing a channel capacity fluctuation value which is directly related to sizes, vertical distances and wavelengths of transceiving antennas; establishing a relation between the channel capacity and the channel capacity fluctuation value when the transceiving antennas are under the head-on condition; constructing an offset channel capacity fluctuation value; carrying out approximation on the average channel capacity in the whole region by utilizing the offset channel capacity fluctuation value; obtaining the optimal channel capacity fluctuation value under the condition of the maximum average channel capacity; and according to the optimal channel capacity fluctuation value, obtaining a relation of the sizes of the transceiving antennas. According to the invention, the superior size of the antenna array can be obtained under the ultralow complexity, so that the method is beneficial for improving the average channel capacity of a system and reducing the fluctuation of the channel capacity in the considered region.

Description

technical field [0001] The invention belongs to the technical field of high-speed wireless communication, in particular to an antenna array size optimization method for 4-antenna transmission and 2-antenna reception to obtain the maximum average channel capacity. Background technique [0002] Multiple-Input and Multiple-Output (MIMO) technology, due to its high spectral efficiency and high power efficiency, has been widely studied and gradually applied, and has become an important candidate technology for wireless communication systems. In a wireless communication system, in order to improve the receiving efficiency of the terminal and expand the coverage of the channel capacity, it is required to have a larger average channel capacity and a smaller channel capacity fluctuation in a certain area. For a wireless communication system that uses a 2-antenna uniform linear array at the receiving end and a planar rectangular array with 4 antennas at the transmitting end, it is nec...
