Problems solved by technology

However, the design of the antenna spacing is very difficult, and the current technology is suitable for scenarios where the relative positions of the transmitter and the receiver are relatively fixed. In the case of relative motion between the transmitter and the receiver, for example, when the receiver is a mobile terminal , it will still cause the problem of not supporting multi-stream transmission

Abstract

An embodiment of the present invention provides a method and device for transmitting signals. The method includes: the sending device determines the target precoding matrix V, where H represents the channel matrix between the sending device and the receiving device, and represents the channel matrix between the sending device and the receiving device. The equivalent channel matrix between devices, or a diagonal matrix, is related to the transmission distance D between the sending device and the receiving device and the dipole spacing of the antenna of the receiving device; the sending device is based on the target precoding matrix V, to send a signal to the receiving device. Since the corresponding channel satisfies or is a characteristic of a diagonal matrix, the corresponding channel can support the transmission of multiple data streams. Therefore, the method and device for transmitting signals provided by the embodiments of the present invention can support multiple data streams transmission.

Description

technical field [0001] The present invention relates to the field of communications, and more particularly, to a method and device for transmitting signals. Background technique [0002] In a multiple-input multiple-output (Multiple-Input Multiple-Output, referred to as "MIMO") system, it is assumed that the transmitting end has N transmitting antennas, and the receiving end has N receiving antennas, and N is an integer greater than 1. In the multipath channel In the environment, the signal received by the receiving antenna may experience different channel transmission, and the correlation between these channels is small. When the transmitting end sends N data streams to the receiving end, that is, N different transmitting antennas send different During the data stream, each receiving antenna at the receiving end can decompose the N data streams, that is, the transmission of multiple data streams is realized, for example, when N is equal to 2, the transmission of double data...
