Problems solved by technology
However, the above two examples are based on simulation and have no theoretical basis, and the dynamic mode switching algorithm in the second example only considers choosing between the two algorithms. At the same time, the methods in the above two examples It can only be applied in a specific antenna configuration environment. For example, the simulation settings are based on the base station with four antennas, and the users in the cell are all equipped with four antennas.

Embodiment Construction
[0032] Such as figure 1 As shown, the dynamic mode switching method based on diversity and multiplexing gain compromise in the interference network of the present invention, the interference network includes a wireless communication system composed of two cells, each cell has a base station and two cell active users ; the method includes the following steps:
[0033] Step 1. The base station in each cell sends the training sequence to the active users in the two cells it serves. After receiving the training sequence sent by the base station, the active users in the cell perform channel estimation and feed back channel state information and signal-to-noise ratio to the base stations it serves;
[0034] Step 2. The base station in each cell judges the transmission mode according to the signal-to-noise ratio (SNR) of active users in the cell received by it. The specific process is as follows:
[0035] Step 201. Determine whether the condition SNR≥12dB is met. When the condition...

The invention discloses a dynamic mode switching method based on a compromise between diversity and multiplexing gain in an interference network. After receiving the training sequence sent by the base station, the user performs channel estimation and feeds back channel state information and signal-to-noise ratio to the base station serving it; 2. The base station in each cell bases itself on the received signal-to-noise ratio of active users in the cell SNR, judging the transmission mode; 3. The transmission mode using the interference alignment method; 4. The transmission mode using the first interference suppression method; 5. The transmission mode using the second interference suppression method; 6. Using the orthogonal multiplexing method the transmission mode. The method of the invention has simple steps, is convenient to implement, has a wide application range, can obtain better transmission performance, has strong practicability, good use effect, and is convenient for popularization and use.
Description
technical field [0001] The invention belongs to the technical field of wireless communication, and in particular relates to a dynamic mode switching method based on a compromise between diversity and multiplexing gain in an interference network. Background technique [0002] In recent years, the development speed of wireless communication is rapid, the fourth generation mobile communication system has been commercialized on a large scale, and the research on the fifth generation mobile communication system is also widely carried out in the world. The deployment of cells in wireless communication systems is becoming more and more dense, and the resulting interference between cells is also becoming more and more serious. For the theoretical research on the dense cell system, the theoretical model in information theory is the interference channel. In recent years, great progress has been made in theoretical research on interference channels. Theoretical studies show that inte...
