Embodiment approach 2

[0183] In addition to the above-mentioned constant extension implementation 1, when L=2n-1, (L-1) / 2 constant extension frequencies can be added on the basis of L independent extension frequencies to obtain the following: Figure 17 In the interference alignment results shown, the degree of freedom of expansion per cell unit is dof=(4L-2) / (3L-1).

[0184] When L=2n, a basic unit is composed of L independent spread frequencies and L / 2 constant spread frequencies, as follows Figure 18 Interference alignment results shown. The total receiving dimension is 3L, the occupied dimension is 3L-1, and one dimension is free. At this time, the degree of freedom of expansion per cell unit is dof=(4L-2) / 3L. Then, the above unit is repeated (3L-1) times, and the data stream in the basic unit can be sent 3L times. The degrees of freedom expanded per cellular unit are

[0185] The comparison of the degree of freedom of unit expansion after implementing constant expansion and without cons...

Abstract

The invention provides a signal processing method, equipment and system. The signal processing method comprises the following steps: receiving uplink signals which comprises the signals obtained by interfering and aligning target signals to be sent by a first mobile terminal according to a precoding matrix and interference signals sent by at least two mobile terminals of an neighboring cell, decoding the uplink signals according to a decoding matrix and obtaining the target signals, wherein the precoding matrix and the decoding matrix are obtained according to the global channel state information of the first mobile terminal and the at least two mobile terminals on an independent expansion channel and a constant expansion channel, and the interference signals and the target signals on the constant expansion channel utilize the dimensionality which is not utilized by the independent expansion channel. The technical scheme of the embodiment of the invention is in line with the actual scene of an actual communication system and is highly practical.

Description

technical field [0001] Embodiments of the present invention relate to the technical field of wireless communication, and in particular, to a signal processing method, device, and system. Background technique [0002] In a cellular network, the signal interference problem of adjacent cells at the cell edge is a relatively common problem in wireless communication technology. [0003] In order to effectively deal with interference, in the past two years, a new interference processing technology, that is, interference alignment technology, has been proposed to deal with interference and obtain effective target signals. Interference alignment technology does not require data interaction between cells; instead, it compresses the dimensions of the interference space into as few dimensions as possible at the receiving end, thereby leaving more dimensions for useful signals. Currently, research on interference alignment mainly focuses on the K-pair user scenario. Moreover, the inte...
