Background
With the continuous development of communication technology, the frequency band supported by a communication system is gradually widened, so that impedance matching needs to be implemented on all frequency points and frequency bands in the frequency band in the current communication system, wherein impedance matching means that the internal resistance of a signal source of the communication system is equal to the characteristic impedance of a signal transmission line in size and in phase.
However, one or more frequency points and/or frequency bands are often mismatched, i.e., the internal impedance of the signal source is different from the characteristic impedance of the signal transmission line, so that the information transmission efficiency of the entire communication system is reduced. In the prior art, mismatched frequency points and/or frequency bands in a communication system can be eliminated by means of re-allocating antennas; or, aiming at the problem of transmission mismatch, the matching condition of the output of the power amplifier in the transmission module is adjusted, then aiming at the problem of reception mismatch, the matching condition of the input of the transceiver chip is adjusted, and finally, the matching index is determined according to the matching conditions of the input and the output of the transceiver chip, so as to complete the matching operation of the mismatch node and/or the frequency band.
However, in the prior art, if the antennas are reconfigured for a very small number of mismatched nodes and/or frequency bands, a lot of manpower and time are required, and other normal frequency points and/or frequency bands may be affected; if the matching index is determined according to the output and received matching conditions, the operation required is complicated, and the problem of mismatched frequency points and/or frequency bands in the communication system cannot be thoroughly solved.

Example one
The embodiment provides a communication transceiving front-end system, which is used for solving the technical problem that the operation process of matching mismatched frequency points and/or frequency bands in a communication system in the prior art is relatively complicated.
As shown in fig. 2, which is a schematic structural diagram of the front-end communication transceiver system provided in this embodiment, the front-end communication transceiver system 10 includes: the antenna 101, the front-end matching module 102, the radio frequency module 103, the mismatch correction module 104, and the matching circuit 1041 and the GPIO control module 1042 in the mismatch correction module 104.

The front-end matching module is used for carrying out impedance matching on communication signals in a preset frequency band; the mismatch correction module is used for replacing the front-end matching module to carry out impedance matching on the communication signal of at least one frequency point and/or frequency band when the front-end matching module is used for carrying out mismatch on the communication signal of at least one frequency point and/or frequency band in the preset frequency band.
Optionally, the mismatch correction module includes a plurality of matching circuits, and each matching circuit is configured to perform impedance matching on a communication signal at one frequency point or frequency band.
Optionally, when the front-end matching module mismatches the communication signal of at least one frequency point and/or frequency band in the preset frequency band, the mismatch correction module is configured to replace the front-end matching module to perform impedance matching on the communication signal of at least one frequency point and/or frequency band.
Specifically, when some or several frequency points and/or frequency bands in the communication transceiving front-end system are mismatched, the communication transceiving front-end system performs matching circuit allocation on the identified mismatched frequency points and/or frequency bands to replace a front-end matching module to perform impedance matching on communication signals of the mismatched frequency points and/or frequency bands, so that the transmission efficiency of the communication signals is improved.
Each matching circuit can only be allocated to one mismatched frequency point or one mismatched frequency band.
Illustratively, if the mismatch correction module in the communication transceiving front-end system includes two matching circuits, which are a first matching circuit and a second matching circuit, respectively, and the preset frequency band used by the front-end matching module is 600M-1G, when both the 600M-650M frequency band and the 900M frequency band are mismatched, the 600M-650M mismatched frequency band is allocated to the first matching circuit, and the 900M mismatched frequency band is allocated to the second matching circuit, so as to perform impedance matching on the communication signals of the mismatched 600M-650M frequency band and the 900M frequency band.
When the number of mismatch frequency points and/or frequency bands in the communication transceiving front-end system is greater than the number of matching circuits in the mismatch correction module, an operator is required to debug the antenna again according to the current actual requirement. The number of matching circuits in the mismatch correction module is set according to actual requirements, and this embodiment is not limited.
Optionally, the circuit form of the plurality of matching circuits comprises at least one or more of: t-type and pi-type.
As shown in fig. 3, the T-type matching circuit provided in this embodiment is configured such that R, C and the L device in the T-type matching circuit are connected in series-parallel-series, and as shown in fig. 4, the pi-type matching circuit provided in this embodiment is configured such that R, C and the L device in the pi-type matching circuit are connected in parallel-series-parallel.
Specifically, the matching circuit comprises at least one T-type circuit and/or pi-type circuit, and is mainly used for adjusting the impedance of mismatched frequency points or frequency bands in the matching circuit to replace a front-end matching module to perform impedance matching on communication signals of mismatched frequency points or frequency bands, so that the transmission efficiency of the communication signals is improved.
The number of T-type circuits and/pi-type circuits in the matching circuit is set by an operator according to actual requirements of mismatched frequency points or frequency bands in the matching circuit, and this embodiment is not limited.
Optionally, when the front-end matching module mismatches the communication signal of at least one frequency point and/or frequency band in the preset frequency band, the front-end matching module is further configured to perform impedance matching on the communication signal that is not mismatched in the preset frequency band.
Specifically, when some or several frequency points and/or frequency bands in the communication transceiving front-end system are mismatched, the communication transceiving front-end system performs matching circuit allocation on the identified mismatched frequency points and/or frequency bands to replace a front-end matching module to perform impedance matching on communication signals of the mismatched frequency points and/or frequency bands. The communication signals of the frequency points and/or frequency bands which are not mismatched in the preset frequency band (the frequency points and/or frequency bands except the mismatched frequency points and/or frequency bands) are subjected to impedance matching based on the front-end matching module pair, so that the transmission of the communication signals is completed.
Optionally, the GPIO control module in the mismatch correction module is configured to establish a connection relationship between at least one matching circuit corresponding to at least one frequency point and/or frequency band and the antenna and the radio frequency module when the front-end matching module is mismatched with the communication signal of at least one frequency point and/or frequency band in the preset frequency band.
Specifically, the GPIO control module is configured to connect the matching circuit to the antenna and connect the matching circuit to the radio frequency module, so as to achieve normal transmission of a communication signal at a frequency point or a frequency band in the matching circuit.
Optionally, the GPIO control module establishes a connection relationship between at least one matching circuit corresponding to at least one frequency point and/or frequency band and the antenna, and the radio frequency module, according to the received control signal; the control signal is used for indicating the communication signal mismatch of at least one frequency point and/or frequency band in the preset frequency band.
The GPIO control module comprises a first GPIO and a second GPIO, the first GPIO and the second GPIO respectively comprise a first register and a second register, the first register and the second register determine the connection relation between the matching circuit and the antenna as well as the radio frequency module according to a control signal of the reading pin, wherein the control signal refers to the level.
Exemplarily, if the mismatch correction module in the communication transceiving front-end system includes three matching circuits, which are a first matching circuit, a second matching circuit and a third matching circuit, respectively, where two ports of the first matching circuit are 1 port and 4 ports, two ports of the second matching circuit are 2 ports and 5 ports, respectively, and two ports of the third matching circuit are 3 ports and 6 ports, respectively, where the positional relationship between the first GPIO, the second GPIO and the above 1-6 ports is shown in fig. 2, then the logical truth table of the corresponding control signals of the GPIO control module and the ports of the matching circuits is shown in the following table:
| first GPIO | Second GPIO | Port connection |
| 1 (high level) | 0 (Low level) | 1 Port-4 Port |
| 0 (Low level) | 1 (high level) | 2-port-5-port |
| 1 (high level) | 0 (Low level) | 3 Port-6 Port |
For example, assuming that a mismatched frequency point exists in the communication transceiving front-end system, the mismatch correction module allocates the first matching circuit to the mismatched frequency point, sets the level of the first GPIO pin to high, sets the level of the second GPIO pin to low, thereby connecting the first matching circuit to the antenna, and connects the first matching circuit to the radio frequency module, so as to implement normal transmission of the communication signal of the frequency point in the first matching circuit. When two mismatched frequency points exist in the front-end communication transceiving system, namely a first mismatched frequency point and a second mismatched frequency point, the first matching circuit is allocated to the first mismatched frequency point by the mismatch correction module, the second matching circuit is allocated to the second mismatched frequency point, pin levels of the first GPIO and the second GPIO in the GPIO control module are set according to the logic truth table, and the like until the mismatched frequency points and/or frequency bands in the front-end communication transceiving system are all allocated to the matching circuits.
Optionally, the GPIO control module establishes a connection relationship between at least one matching circuit corresponding to at least one frequency point and/or frequency band and the antenna and the radio frequency module according to the mapping relationship;
the mapping relation comprises a plurality of frequency points and/or frequency bands and the corresponding relation between each frequency point or frequency band and the matching circuit.
For example, when the preset frequency band is 600M-1G, the mapping relationship between the mismatched frequency points and/or frequency bands and the matching circuit may be as shown in the following table:
the mapping relationship may be preset by an operator, or may be adjusted in real time according to actual conditions.
| Frequency band | 600M-750M | 751M-900M | 901M-1G |
| Matching circuit | First matching circuit | Second matching circuit | Third matching circuit |
When the mismatch frequency point is 650M, the GPIO control module allocates the first matching circuit to the mismatch frequency point according to the mapping relationship, and at this time, the first GPIO and the second GPIO in the GPIO control module connect the first matching circuit to the antenna and the radio frequency module according to the logic truth table, so as to achieve normal transmission of the communication signal of the mismatch frequency point.
In the front-end communication transceiver system provided in this embodiment, the antenna is connected to the radio frequency module based on the front-end matching module, the antenna is further connected to the radio frequency module based on the mismatch correction module, the communication signal in the preset frequency band is transmitted between the antenna and the radio frequency module through the front-end matching module, the front-end matching module is used for performing impedance matching on the communication signal in the preset frequency band, and the mismatch correction module is used for performing impedance matching on the communication signal in at least one frequency point or frequency band instead of the front-end matching module when the front-end matching module is mismatched on the communication signal in at least one frequency point or frequency band in the preset frequency band, so that the front-end communication transceiver system does not need to readjust the antenna when the number of mismatched frequency points and/frequency bands is small, the problem of front end mismatch of a communication transceiving system is solved, the method is simple, the operation is easy, the flexibility is high, other system modules cannot be affected, and meanwhile, the signal transmission efficiency of the whole communication transceiving front end system is improved.
