wherein, the value of the matrix on the left side of the equation represents the value corresponding to the signal which needs to be output finally, and x in the first matrix on the right side of the equation ₃₁ Denotes a seventh coefficient, x ₃₂ Denotes an eighth coefficient, x ₃₃ Denotes the ninth coefficient, x ₃₄ Denotes the tenth coefficient, x ₄₁ Denotes an eleventh coefficient, x ₄₂ Denotes the twelfth coefficient, x ₄₃ Denotes a thirteenth coefficient, x ₄₄ The fourteenth coefficient is expressed, and the second matrix on the right side of the equation represents the corresponding values of the first signal and the second signal obtained by processing the first rf channel and the second rf channel, that is, the following equation relationship can be obtained according to the equation:

namely, the above equation relationship can be calculated

It is understood that, in an actual application process, the number of antennas corresponding to one polarization direction may be 3 columns, 4 columns, or more, and is not limited herein.

In step 203, the base station obtains n target signals according to the n third signals and the n fourth signals.

After the base station obtains n third signals and n fourth signals, the base station superposes the n third signals and the n fourth signals respectively to obtain n target signals.

When n is equal to 3, the n third signals include a first coefficient signal, a second coefficient signal and a third coefficient signal, and the n fourth signals include a fourth coefficient signal, a fifth coefficient signal and a sixth coefficient signal, as shown in step 202.

The base station superposes the first coefficient signal and the fourth coefficient signal to obtain a first target signal, the base station superposes the second coefficient signal and the fifth coefficient signal to obtain a second target signal, and the base station superposes the third coefficient signal and the sixth coefficient signal to obtain a third target signal.

It is understood that, in practical applications, multiple columns of antennas may also correspond to one polarization direction, for example, 4 columns of antennas correspond to one polarization direction, that is, n is 4.

When n is 4, it can be seen from step 202 that the n third signals include a seventh coefficient signal, an eighth coefficient signal, a ninth coefficient signal, and a tenth coefficient signal, and the n fourth signals include an eleventh coefficient signal, a twelfth coefficient signal, a thirteenth coefficient signal, and a fourteenth coefficient signal.

When m columns of antennas in one polarization direction of a base station receive signals sent by terminal equipment in an area corresponding to the polarization direction, the base station receives m fifth signals through the m columns of antennas respectively, the fifth signals are signals sent by the terminal equipment in the area, and m is an integer greater than or equal to 3.

For example, when m is equal to 3, the 3 columns of antennas include a first antenna, a second antenna, and a third antenna, and the base station receives a first reception signal through the first antenna, a second reception signal through the second antenna, and a third reception signal through the third antenna, that is, the 3 fifth signals include the first reception signal, the second reception signal, and the third reception signal.

For example, when m is equal to 4, the 4 columns of antennas include a first antenna, a second antenna, a third antenna, and a fourth antenna, and the base station receives a fourth reception signal through the first antenna, a fifth reception signal through the second antenna, a sixth reception signal through the third antenna, and a seventh reception signal through the fourth antenna.

In step 206, the base station processes the m fifth signals to obtain m first reception target signals and m second reception target signals.

When the base station receives the m fifth signals, the base station multiplies the values corresponding to the m fifth signals by the corresponding coefficients to obtain m first receiving target signals and m second receiving target signals.

When the base station has 3 columns of antennas in one polarization direction, then m at this time is equal to 3.

The base station multiplies the first received signal by a first coefficient and a fourth coefficient, respectively, to obtain a first coefficient received signal and a fourth coefficient received signal, the base station multiplies the second received signal by a second coefficient and a fifth coefficient, respectively, to obtain a second coefficient received signal and a fifth coefficient received signal, and the base station multiplies the third received signal by a third coefficient and a sixth coefficient, respectively, to obtain a third coefficient received signal and a sixth coefficient received signal.

and the values of a, b and c satisfy the following conditions:

b2-2ac＝0

wherein the values of the matrix on the left side of the equation represent the values corresponding to the three columns of antenna receive signals, and x is in the first matrix on the right side of the equation ₁₁ Denotes the first coefficient, x ₁₂ Denotes the second coefficient, x ₁₃ Denotes the third coefficient, x ₂₁ Denotes the fourth coefficient, x ₂₂ Denotes the fifth coefficient, x ₂₃ The sixth coefficient is expressed, and the second matrix on the right side of the equation expresses the corresponding values of the signals received by the first rf channel and the second rf channel last, i.e. the following equation relationship can be obtained according to the equation:

that is, the above equation relationship can be calculated

To say thatIt should be understood that, in order to normalize the matrix vector, the above coefficients may be further multiplied

The base station multiplies the fourth received signal by a seventh coefficient and an eleventh coefficient respectively to obtain a seventh coefficient received signal and an eleventh coefficient received signal, the base station multiplies the fifth received signal by an eighth coefficient and a twelfth coefficient respectively to obtain an eighth coefficient received signal and a twelfth coefficient received signal, the base station multiplies the sixth received signal by a ninth coefficient and a thirteenth coefficient respectively to obtain a ninth coefficient received signal and a thirteenth coefficient received signal, and the base station multiplies the seventh received signal by a tenth coefficient and a fourteenth coefficient respectively to obtain a tenth coefficient received signal and a fourteenth coefficient received signal.

in the embodiment of the present application, when the seventh coefficient, the eighth coefficient, the ninth coefficient, the tenth coefficient, the eleventh coefficient, the twelfth coefficient, the thirteenth coefficient, and the fourteenth coefficient satisfy the above values, the loss of the power of the signal in the transmission process of the radio frequency channel can be reduced, and it is ensured that the signal is effectively received through the antenna.

wherein the values of the matrix on the left side of the equation represent the values corresponding to four columns of antenna received signals, and x is in the first matrix on the right side of the equation ₃₁ Denotes a seventh coefficient, x ₃₂ Denotes an eighth coefficient, x ₃₃ Denotes the ninth coefficient, x ₃₄ Denotes the tenth coefficient, x ₄₁ Denotes the eleventh coefficient, x ₄₂ Denotes the twelfth coefficient, x ₄₃ Denotes a thirteenth coefficient, x ₄₄ The fourteenth coefficient is expressed, and the second matrix on the right side of the equation represents the corresponding value of the last received signal of the first rf channel and the second rf channel, i.e. the following equation relationship can be obtained according to the equation:

namely, the above equation relationship can be calculated

In step 207, the base station obtains a sixth signal and a seventh signal from the m first reception target signals and the m second reception target signals.

After the base station obtains the m first reception target signals and the m second reception target signals, the base station superposes the m first reception target signals and the m second reception target signals to obtain a sixth signal and a seventh signal.

For example, when there are three columns of antennas in one polarization direction, i.e., m-3.

As shown in step 206, when n is 3, the m first reception target signals include a first coefficient reception signal, a second coefficient reception signal, and a third coefficient reception signal, and the m second reception target signals include a fourth coefficient reception signal, a fifth coefficient reception signal, and a sixth coefficient reception signal, the base station superimposes the first coefficient signal, the second coefficient signal, and the third coefficient signal to obtain a sixth signal, and the base station superimposes the fourth coefficient signal, the fifth coefficient signal, and the sixth coefficient signal to obtain a seventh signal.

For example, when there are four columns of antennas in one polarization direction, i.e., m is 4.

As shown in step 206, when n is 4, the m first reception target signals include a seventh coefficient reception signal, an eighth coefficient reception signal, a ninth coefficient reception signal, and a tenth coefficient reception signal, and the m second reception target signals include an eleventh coefficient reception signal, a twelfth coefficient reception signal, a thirteenth coefficient reception signal, and a fourteenth coefficient reception signal, the base station superimposes the seventh coefficient signal, the eighth coefficient signal, the ninth coefficient signal, and the tenth coefficient signal to obtain a sixth signal, and the base station superimposes the eleventh coefficient signal, the twelfth coefficient signal, the thirteenth coefficient signal, and the fourteenth coefficient signal to obtain a seventh signal.

In step 208, the base station processes the sixth signal and the seventh signal through the first rf channel and the second rf channel, respectively.

After the base station processes the sixth signal and the seventh signal, the base station respectively performs low noise amplification and down-conversion processing on the sixth signal and the seventh signal through a first radio frequency channel and a second radio frequency channel, then converts the down-converted sixth signal and seventh signal into digital signals, then performs MIMO beam forming processing on the digital signals, and finally performs demodulation processing through a base band at the rear end of the base station.

It should be noted that, steps 201 to 204 are steps executed when the base station sends a signal, and steps 205 to 208 are steps executed when the base station receives a signal, and in an actual application process, only steps 201 to 204 may be executed, step 205 to step 208 are not executed, or only step 205 to step 208 are executed, step 201 to step 204 are not executed, and specific details are not limited herein.

In this embodiment, the base station processes the first signal and the second signal processed by the first radio frequency channel and the second radio frequency channel in one polarization direction to obtain n target signals, and sends the n target signals through n rows of antennas in the polarization direction, that is, the half-power width corresponding to one logic port is about 65 degrees, because one logic port corresponds to n rows of antennas, the half-power width of one row of antennas can be about 90 degrees, so that the equivalent spacing between the antennas is less than or equal to 0.5 wavelength, a strong beam grating lobe generated by sending a data beam is avoided, and the efficiency of data transmission is improved.
