Abstract

The invention discloses a realizing method and device of multiple transmit antenna MIMO(multi-input multi-output) system, comprising: obtaining and copying antenna MIMO(multi-input multi-output) data, storing the MIMO(multi-input multi-output) data and the copied data to be cyclic shift sequence; determining the current cyclic address parameters and cyclically shifting the cyclic shift sequences by the current cyclic address parameters, getting corresponding cyclic shift sequence results of the multiple transmitting antenna. The invention also provides a realizing device of MIMO (multi-input multi-output) MIMO (multi-input multi-output) system based on the method. The invention is characterized by setting each antenna different cyclic shift parameters, making the original antenna (for example, 2 antennas) MIMO (multi-input multi-output) extend to a plurality of antennas (for example, 4, 6...2N antennas) and improving the MIMO (multi-input multi-output) gain.

Description

technical field [0001] The present invention relates to the communication field, and in particular, to a method and device for realizing a Multiple Input Multiple Output (Multiple Input Multiple Output, MIMO for short) system with multiple transmitting antennas. Background technique [0002] Recently, the multiple input multiple output MIMO (Multiple Input Multiple Output, referred to as MIMO) technology in the field of modern wireless communication (communication link using MIMO technology is vividly called volume-to-volume), to distinguish There have been some major breakthroughs over traditional wire links). Its outstanding feature is that it greatly improves the system capacity. Since the future wireless network needs to be connected to the Internet, this technical feature is very important for the future wireless network. [0003] In fact, the definition of MIMO is very simple. For a wireless communication system, if there are multiple transmitting antennas and receiv...
