in step 101, the electronic device detects a first received signal strength of a first receiving path, where the first receiving path is an open receiving path among a plurality of receiving paths.
In an embodiment of the present invention, any receiving path of the electronic device may include: the LNA in each receiving channel is respectively connected with a radio frequency transceiver, the radio frequency transceiver is connected with a modem, and the modem is connected with a baseband processor. The antenna is used for receiving signals, the LNA is an amplifier capable of suppressing noise, the LNA is low in noise coefficient and capable of reducing noise and amplifying the signals and transmitting the signals subjected to the noise reduction and amplification to the radio frequency transceiver, the radio frequency transceiver transmits the signals to the modem, the modem is used for modulating and demodulating the received signals and transmitting the signals subjected to the modulation and demodulation to the baseband processor, and the baseband processor can convert current receiving power into first receiving signal strength after receiving the signals.
Currently, the opened receiving path in the electronic device is the first receiving path, and in general communication services, only one receiving path is usually opened. Signals in the current communication service can be received by the antenna in the first receiving path, and the signals reach the LNA after being filtered by the filter, and at this time, the LNA in the first receiving path is already operated at the most suitable gain level. Then, the signal is amplified by the LNA and transmitted to the rf transceiver, the rf transceiver sends the signal to the modem for modulation and demodulation, the modem sends the modulated and demodulated signal to the baseband processor, and the baseband processor can convert the current received power into the first received signal strength after receiving the signal.
In the embodiment of the present invention, the pre-stored difference between the received signal strengths of the first receiving path and the at least one target receiving path may be obtained by respectively measuring the received signal strengths of the receiving paths and then performing a difference operation on every two received signal strengths under the condition that all receiving paths are opened in advance.
In a specific application, the number of target receiving paths may be determined according to the requirement of the current communication service, for example, 3 receiving paths need to be opened simultaneously when processing the current communication service, and if the current first receiving path is opened, any 2 receiving paths that are not opened are the target receiving paths.
In addition, the received signal strength difference between the receiving paths does not change greatly along with the strength change of the received signal, so the received signal strength difference between the receiving paths is a stable value.
In step 103, the electronic device determines a target received signal strength of each target receiving path according to the first received signal strength and the difference value of the respective received signal strengths.
In the embodiment of the present invention, the electronic device may subtract the first received signal strength from each received signal strength difference, so as to obtain the current target received signal strength of each target receiving path.
And step 104, the electronic equipment determines a gain level corresponding to each target receiving path according to the strength of each target receiving signal.
In the embodiment of the present invention, different target received signal strengths correspond to different gain levels, and therefore, the gain level corresponding to each target receiving path can be determined according to each target received signal strength.
In step 105, the electronic device controls the LNAs in each target receive path to be adjusted to the corresponding gain stages, respectively.
In an embodiment of the present invention, the LNA in each target receive path in the electronic device may be adjusted to a corresponding gain stage, respectively, wherein the LNA in the first receive path is already operating at the most suitable gain stage without adjustment. After the adjustment is completed, the LNAs in the target receiving paths can directly and normally operate under the corresponding gain stages, and when the first receiving path and each target receiving path are both opened, the target signals to be received can be normally received by the first receiving path and each target receiving path, and subsequent transmission and processing can be performed.
In the embodiment of the present invention, the electronic device may first detect a first received signal strength of a first receiving path, where the first receiving path is an open receiving path in the plurality of receiving paths. Then, the pre-stored difference of the received signal strength between the first receiving path and at least one target receiving path can be read, wherein the at least one target receiving path is at least one receiving path that is not opened in the plurality of receiving paths. Then, the electronic device may determine the target received signal strength of each target receiving path according to the first received signal strength and the difference between the respective received signal strengths, determine a gain stage corresponding to each target receiving path according to each target received signal strength, and control the LNA in each target receiving path to adjust to the corresponding gain stage respectively. In the embodiment of the invention, the electronic device can determine the gain stage corresponding to each target receiving path according to the target receiving signal strength of each target receiving path, and control the LNA in each target receiving path to be directly adjusted to the corresponding gain stage, so that the LNA in each target receiving path does not need to be adjusted to the corresponding gain stage step by step, the adjusting time of the LNA gain stage is shortened, the phenomenon that the LNA gain stage is blocked due to overlong adjusting time in the signal receiving process can be avoided, and the overall time of signal processing is shortened.
Example two
Referring to fig. 2, a flowchart of a gain stage adjustment method according to a second embodiment of the present invention is shown, where the method is applied to an electronic device, where the electronic device includes a plurality of receiving paths, and each receiving path includes a low noise amplifier LNA, and the method specifically includes the following steps:
in step 201, the electronic device receives a test signal through a plurality of receiving paths when the plurality of receiving paths are all open.
In the embodiment of the invention, the electronic device can open a plurality of receiving paths, and then can transmit the test signal to the electronic device through the external device, and the electronic device can receive the test signal through the antenna of each receiving path. The embodiment of the invention does not limit the signal intensity frequency and the like of the test signal.
In step 202, the electronic device detects the received signal strength of each receiving channel during the process of receiving the test signal.
In the embodiment of the invention, each receiving channel receives a test signal, the test signal reaches an LNA after being filtered by a filter, the test signal is amplified by the LNA and then is transmitted to a radio frequency transceiver, the radio frequency transceiver sends the test signal to a modem, the modem modulates and demodulates the test signal, the radio frequency transceiver sends the signal to the modem, the modem modulates and demodulates a target signal, the modulated and demodulated target signal is sent to a baseband processor, and the baseband processor can convert the current receiving power into the first receiving signal intensity after receiving the signal.
In step 203, the electronic device determines the difference in received signal strength between each two receive paths.
In the embodiment of the present invention, the electronic device may subtract the received signal strength of each receiving path from the received signal strength of other receiving paths, respectively, to obtain a received signal strength difference between every two receiving paths. It should be noted that the difference in the received signal strength between the receiving path 1 and the receiving path 2 is different from the difference in the received signal strength between the receiving path 2 and the receiving path 1, and the determination may be performed in any embodiment of the present invention.
For example, when the electronic device has 4 receiving paths, the received signal strength P1 of the receiving path 1 may be-80 dBm (decibel-milliwatt), the received signal strength of the receiving path 2 may be-83 dBm, the received signal strength of the receiving path 3 may be-83.5 dBm, and the received signal strength of the receiving path 4 may be-70 dBm. Referring to table 1 below, the received signal strength difference d between the receive path 1 and the receive path 212May be 3dBm and the difference d in received signal strength between receive path 2 and receive path 121The value is-3 dBm, and the signs of the two are opposite, as shown in table 1, the difference between the received signal strengths of any two other receiving paths is the same rule, and will not be described herein.
TABLE 1
| Receiving path 1 | Receiving path 2 | Receiving path 3 | Receiving path 4 | |
| Receiving path 1 | / | d12＝3dBm | d13＝3.5dBm | d14＝-10dBm |
| Receiving path 2 | d21＝-3dBm | / | d23＝0.5dBm | d24＝-13dBm |
| Receiving path 3 | d31＝-3.5dBm | d32＝-0.5dBm | / | d34＝-13.5dBm |
| Receiving path 4 | d41＝10dBm | d42＝13dBm | d43＝13.5dBm | / |
It should be noted that, in the embodiment of the present invention, only the difference between the received signal strengths of every two receiving paths as shown in table 1 is taken as an example for description, and the difference between the received signal strengths as shown in table 1 is not limited to the present invention.
Further, after determining the difference between the received signal strengths of each two receiving paths, the electronic device may store the respective received signal strength differences in the electronic device.
In this embodiment of the present invention, steps 201 to 203 may be performed at least twice, so as to obtain at least two received signal strength differences between every two receiving paths, the electronic device may determine an average value of the at least two received signal strength differences between the receiving path 1 and the receiving path 2, an average value of the at least two received signal strength differences between the receiving path 2 and the receiving path 3, and so on, until determining an average value of the received signal strength differences between every two receiving paths, and then may store the average value of the received signal strength differences between every two receiving paths into the electronic device, so as to improve the confidence of the received signal strength differences.
In step 204, the electronic device detects a first received signal strength of a first receiving path, where the first receiving path is an open receiving path among the plurality of receiving paths.
In practical applications, when the electronic device has 4 receiving paths, if the receiving path 1 is in an opened state at this time, the receiving path 1 is the first receiving path, and the electronic device can detect the first received signal strength of the receiving path 1. At this time, the corresponding scene is the switching from the single-path receiving mode to the 4-path receiving mode.
In step 205, the electronic device reads the pre-stored difference between the received signal strength of the first receiving path and the received signal strength of at least one target receiving path, where the at least one target receiving path is at least one receiving path that is not opened among the plurality of receiving paths.
In practical applicationFor example, when the electronic device has 4 receiving paths and the receiving path 1 is the first receiving path that is currently opened, the target receiving paths that need to be opened may be the receiving path 2, the receiving path 3 and the receiving path 4, and the electronic device may read the pre-stored signal strength difference d between the receiving path 1 and the receiving path 2123dBm, the signal strength difference d between the receiving path 1 and the receiving path 3133.5dBm, and the difference d between the signal strengths of the receiving path 1 and the receiving path 414＝-10dBm。
For another example, when the electronic device has 4 receiving paths and the receiving path 2 is the first receiving path that is currently opened, the target receiving paths that need to be opened may be the receiving path 1, the receiving path 3, and the receiving path 4, and the electronic device may read the pre-stored signal strength difference d between the receiving path 2 and the receiving path 121-3dBm, signal strength difference d between receiving path 2 and receiving path 3230.5dBm, and the difference d between the signal strengths of the receiving path 2 and the receiving path 424＝-13dBm。
In step 206, the electronic device subtracts the first received signal strength from each received signal strength difference, so as to obtain a target received signal strength of each target receiving path.
In the embodiment of the present invention, since the difference in the received signal strength between the receiving paths does not change greatly with the change in the strength of the received signal, the difference in the received signal strength between the receiving paths is a relatively stable value, and therefore, the target received signal strength of each target receiving path obtained by subtracting the first received signal strength from each received signal strength difference is substantially the same as the actual received signal strength of each target receiving path.
For example, when the electronic device has 4 receiving paths and the receiving path 1 is the first receiving path that is currently opened, the electronic device may change the first received signal strength P1' to-70 dBm and d12The subtraction is performed at 3dBm to obtain a target received signal strength P2 'of-73 dBm of the reception path 2, and the electronic device may subtract the first received signal strength P1' of-70 dBm and d133.5dBm inThe line subtraction may be performed to obtain a target received signal strength P3 '— 73.5dBm of the reception path 3, and the electronic device may obtain the first received signal strength P1' — 70dBm and d14The subtraction is performed at-10 dBm, and the target received signal strength P4' of the reception path 4 is obtained at-60 dBm.
In step 207, the electronic device determines the received signal strength range to which each target received signal strength belongs.
In the embodiment of the present invention, a preset gain level comparison table may be stored in the electronic device, where the preset gain level comparison table may store a corresponding relationship between a received signal strength range and a gain level, and the received signal strength ranges corresponding to different gain levels are different. The electronic device may first determine a received signal strength range to which each target received signal strength belongs in the preset gain level look-up table, respectively. In practical applications, the range of the received signal strength corresponding to each target received signal strength may be the same or different.
For example, referring to table 2 below, a gain level comparison table is shown, wherein the gain level is divided into 5 levels, and the received signal strength range of each gain level is different.
TABLE 2
| Received Signal Strength Range (Unit: dBm) | Gain stage |
| [-90,-80] | Zero-order gain stage (maximum gain stage) |
| [-79,-70] | First gain stage |
| [-69,-60] | Two-stage gain stage |
| [-59,-50] | Three-stage gain stage |
| [-49,-40] | Four-stage gain stage (minimum gain stage) |
It should be noted that, the embodiment of the present invention is described by taking the preset gain level comparison table shown in table 2 above as an example, and the gain level and the received signal strength range in the preset gain level comparison table shown in table 2 above do not limit the present invention.
For example, referring to table 2 above, the electronic device may determine that the target received signal strength P2 ' ═ 73dBm of the reception path 2 belongs to the received signal strength range of [ -79, -70], the target received signal strength P3 ' ═ 73.5dBm of the reception path 3 belongs to the received signal strength range of [ -79, -70], the target received signal strength P4 ' ═ 60dBm of the reception path 4 belongs to the received signal strength range of [ -69, -60],
in step 208, the electronic device queries the gain level corresponding to each received signal strength range according to the preset gain level comparison table.
In the embodiment of the present invention, the electronic device may query, from the preset gain level comparison table, a gain level corresponding to a received signal strength range to which each target received signal strength belongs.
For example, the electronic device may find the gain level corresponding to the received signal strength range [ -79, -70] as the first-level gain level and the gain level corresponding to the received signal strength range [ -69, -60] as the second-level gain level from the preset gain level comparison table shown in table 2 above.
In step 209, the electronic device controls the LNAs in each target receive path to be adjusted to the corresponding gain stages, respectively.
In the embodiment of the present invention, the LNA in each target receiving path in the electronic device may be respectively adjusted to a corresponding gain stage, after the adjustment is completed, the LNA in each target receiving path may directly and normally operate under the corresponding gain stage, and when each target receiving path is opened, the target signal may be normally received by each target receiving path, and subsequent transmission and processing may be performed.
In practical applications, taking a large-scale mass-produced LNA as an example, the LNA usually needs a time duration of about 4 μ s (microseconds) for adjusting a gain stage once, if the LNA in each target receiving path is adjusted to a maximum gain stage, that is, a zero-order gain stage, according to the related art, and then is adjusted to a corresponding gain stage step by step from the maximum gain stage, the adjustment process needs to consume 4N μ s for N times, for example, if a certain receiving path needs to be adjusted to a second-order gain stage, 3 times are required for the adjustment process, 12 μ s are required for the adjustment process, and if a certain receiving path needs to be adjusted to a fourth-order gain stage, 5 times are required for the adjustment process, and 20 μ s is required for the adjustment process. If the LNA in each target receiving path is adjusted in gain level according to the method provided by the embodiment of the present invention, the LNA can be directly adjusted to a suitable gain level, and only one adjustment is needed, and the adjustment process only needs to consume 4 μ s.
For example, the electronic device may control the receive path 2 to be turned on, then control the LNA in the receive path 2 to adjust to a one-stage gain stage, the electronic device may control the receive path 3 to be turned on, then control the LNA in the receive path 3 to adjust to a one-stage gain stage, the electronic device may control the receive path 4 to be turned on, then control the LNA in the receive path 4 to adjust to a two-stage gain stage, and then the electronic device may simultaneously receive the target signal through the receive path 1, the receive path 2, the receive path 3, and the receive path 4 when the target signal arrives.
In the embodiment of the invention, the electronic device firstly simultaneously transmits a test signal to a plurality of receiving paths under the condition that a plurality of receiving paths are opened, detects the received signal strength of each receiving path under the condition that each receiving path receives the test signal, determines the received signal strength difference between every two receiving paths, detects the first received signal strength of a first receiving path, wherein the first receiving path is the opened receiving path in the plurality of receiving paths, then the electronic device reads the pre-stored received signal strength difference between the first receiving path and at least one target receiving path, wherein at least one target receiving path is at least one receiving path which is not opened in the plurality of receiving paths, subtracts the first received signal strength and the received signal strength difference respectively to obtain the target received signal strength of each target receiving path, the electronic equipment respectively determines the received signal strength range to which each target received signal strength belongs, and inquires the gain stage corresponding to each received signal strength range according to a preset gain stage comparison table so as to control the LNA in each target receiving path to be respectively adjusted to the corresponding gain stage. In the embodiment of the invention, the electronic device can determine the gain stage corresponding to each target receiving path according to the target receiving signal strength of each target receiving path, and control the LNA in each target receiving path to be directly adjusted to the corresponding gain stage, so that the LNA in each target receiving path does not need to be adjusted to the corresponding gain stage step by step, the adjusting time of the LNA gain stage is shortened, the phenomenon that the LNA gain stage is blocked due to overlong adjusting time in the signal receiving process can be avoided, and the overall time of signal processing is shortened.
