The following describes the technical solutions of the present disclosure and how to solve the above technical problems in specific embodiments. These several specific embodiments may be combined with each other below, and details of the same or similar concepts or processes may not be repeated in some embodiments. Embodiments of the present disclosure will be described below with reference to the accompanying drawings.
The disclosed embodiment provides a method for adjusting a transmission signal of an antenna, which can be executed by a device with an antenna, as shown in fig. 1, and includes the following steps:
s101, acquiring a coupling signal, and determining an adjacent channel leakage ratio ACLR of the coupling signal; the coupling signal is a signal which is output by the transceiver and is divided by the coupler after being subjected to predetermined processing, the first signal is an analog signal converted from a to-be-transmitted digital signal in the transceiver, and the to-be-transmitted digital signal comprises a signal in a channel and a signal in an adjacent channel.
The inventors of the present disclosure consider that the coupled signal is a signal dropped by the coupler, the remaining signal is a signal that the antenna will emit, and the ACLR of the remaining signal is the same as the ACLR of the coupled signal, such that the ACLR of the signal entering the coupler and outputting to the antenna needs to be adjusted if the ACLR of the coupled signal is not satisfactory. Therefore, it is necessary to determine the ACLR of the coupled signal in order to ensure that the ACLR of the transmitted signal of the antenna is satisfactory.
Optionally, in step S101, determining an adjacent channel leakage ratio ACLR of the coupled signal includes: measuring the signal power of the coupling signal in the channel and the signal power of the coupling signal in the adjacent channel; and dividing the signal power of the channel and the signal power of the adjacent channel to obtain the ACLR of the coupled signal.
In practical applications, the power of the coupled signal in the channel and the adjacent channel of the channel can be directly measured.
S102, determining whether the ACLR of the coupling signal is less than a preset target ACLR, and executing the step S103 when the ACLR of the coupling signal is less than the preset target ACLR; when the ACLR of the coupling signal is not less than the preset target ACLR, step S104 is performed.
S103, performing digital filtering on signals of the digital signal to be transmitted in the adjacent channel, and taking the digital signal to be transmitted after the digital filtering as a new digital signal to be transmitted.
In practical applications, the signal output by the transceiver is a digital signal, and then the filtered digital signal is converted into an analog signal and then output. In practical application, the filter can be selected according to specific situations, for example, a Kalman filter, a Butterworth filter or other filters are used for digitally filtering digital signals of adjacent channels, and the digital filter can be selected according to actual scenes to realize digital filtering of the digital signals.
And S104, not filtering the digital signal to be transmitted.
Alternatively, in step S101, the predetermined process includes at least one of the following processes: power amplification processing, filtering processing and power coupling processing.
Optionally, the adjusting method of the present disclosure is a continuous loop process, determining whether the ACLR of the coupling signal is smaller than a preset target ACLR each time the coupling signal is received, and performing the processing of step S103 or step S104 according to the determination result, so as to continuously adjust the ACLR of the coupling signal until the ACLR of the coupling signal is not smaller than the preset target ACLR, thereby meeting the signal requirement. The process of coupling signals transmitted by the antenna is a fast iterative process, and is a closed loop system.
In practical application, a digital signal to be transmitted is converted into an analog signal from a digital signal to obtain a first signal, and the first signal may be sequentially subjected to power amplification, filtering and power coupling to obtain a coupling signal. The coupling signal may be a signal obtained by power coupling, by a coupler, the second signal in a channel and a signal of an adjacent channel according to a predetermined ratio, where ACLR of the second signal and ACLR of the coupling signal are both the same as ACLR of the digital signal to be transmitted. The coupling signal is a coupling value of the second signal, that is, a small portion of the signal is extracted from a path of the second signal, and the coupling value represents a characteristic of the second signal and also represents a characteristic of the digital signal to be transmitted, and is smaller in power value compared with the digital signal to be transmitted, and is equivalent to the digital signal to be transmitted with a small power value.
For example: the digital signal to be transmitted is 20dBm (decibel-milliwatt) and the coupled signal may be only 0.1 dBm. For another example: the signal power of the digital signal to be transmitted in the channel and the signal power of the digital signal to be transmitted in the adjacent channel are respectively 100dBm and 10dBm, the ACLR is 10, if the coupling degree is 10, the coupled signal is respectively 10dBm and 1dBm, namely the coupled signal ACLR is also 10, namely the coupled signal and the ACLR of the digital signal to be transmitted are consistent, then whether the coupled signal meets the requirement or not is determined, namely whether the digital signal to be transmitted meets the requirement or not is determined, then the ACLR of the digital signal to be transmitted is adjusted according to the determination result, and further the ACLR of the coupled signal is adjusted.
The inventor of the present disclosure considers that, in the case that the ACLR of the coupled signal does not meet the requirement, the ACLR of the transceiver for the digital signal to be transmitted needs to be adjusted so that the ACLR of the transmission signal of the antenna meets the requirement. If the ACLR of the to-be-transmitted digital signal corresponding to the coupling signal is adjusted, after the to-be-transmitted digital signal of the transceiver is correspondingly converted into the first signal of the analog signal and is subjected to predetermined processing, the ACLR of the obtained coupling signal is also adjusted accordingly. Since the ACLR of a signal is the result of the division of the signal power on a channel and the signal power on an adjacent channel, reducing the signal power on the adjacent channel increases the signal's ACLR. Therefore, the inventor filters the signals of the digital signal to be transmitted in the adjacent channels, filters out interference signals, and reduces the signal power of the adjacent channels, thereby increasing the ACLR of the digital signal to be transmitted, and further increasing the ACLR of the coupled signal. The method can determine the ACLR of the coupling signal in a loop until the ACLR of the coupling signal reaches a preset target ACLR, which satisfies the signal requirement.
The method comprises the steps of obtaining a coupling signal, then determining the adjacent channel leakage ratio ACLR of the coupling signal, then comparing the ACLR of the coupling signal with a preset target ACLR, when the ACLR of the coupling signal is smaller than the preset target ACLR, representing that the ACLR of the coupling signal does not meet the requirement, digitally filtering signals of a digital signal to be transmitted in an adjacent channel, filtering interference signals, reducing the signal power of the digital signal to be transmitted in the adjacent channel, and increasing the ACLR of the digital signal to be transmitted. Because the coupling signal is output after the digital signal to be transmitted in the transceiver is correspondingly converted into the analog signal, that is, the first signal is divided by the coupler after being subjected to the predetermined processing, the ACLR of the coupling signal is correspondingly increased until the ACLR of the coupling signal is not less than the preset target ACLR, which indicates that the ACLR of the coupling signal meets the requirement.
The coupled signal of the embodiment of the present disclosure is obtained by power coupling the signal in the channel and the signal in the adjacent channel by the coupler according to the predetermined ratio to obtain the coupled signal, and the coupled signal is separated from the second signal, so that the ACLR of the coupled signal is the same as the ACLR of the second signal, the ACLR of the rest of the signals outside the second signal separated from the coupled signal is the same as the ACLR of the second signal, that is, the ACLR of the third signal is the same as the ACLR of the second signal. When the ACLR of the coupled signal meets the requirement, the ACLR of the third signal also meets the requirement, and the third signal is a transmission signal acquired by the antenna, so that the transmission signal emitted by the antenna meets the requirement.
The method is a closed-loop software debugging method, does not need to increase hardware, does not need to debug equipment, is not limited by a debugging environment, can automatically debug by adopting software, can debug for many times in a circulating way until the ACLR of a first signal output by a transceiver obtains an ideal optimal value, and has a simple debugging process.
The method includes the steps that a coupling signal which is subjected to preset processing and then is separated by a coupler is obtained, a digital signal to be transmitted which is not subjected to preset processing is not directly detected, whether ACLR of the coupling signal subjected to preset processing meets requirements or not is detected, namely whether the rest signals of the coupling signal separated from a second signal by the coupler reach optimal values or not is detected, the rest signals are third signals sent by an antenna, the ACLR of the digital signal to be transmitted of a transceiver is adjusted, the detection result is more accurate, the ACLR of the digital signal to be transmitted of the transceiver is adjusted, the antenna can transmit a transmitting signal which achieves a preset ideal effect, and the performance index of an output signal is improved.
