More specifically, as shown in fig. 5, a schematic structural diagram of another signal processing apparatus provided in this embodiment is shown, and the schematic structural diagram shown in fig. 5 may be a specific implementation manner of the schematic structural diagram shown in fig. 3. The following describes the procedure of receiving and transmitting signals by the signal processing apparatus shown in fig. 5.
1. And (5) signal sending processing.
Specifically, a signal to be transmitted enters the first bridge from a T1 port of the first bridge, the first bridge converts the signal to be transmitted into a first signal and a second signal, and if the first signal is output from a T3 port of the first bridge, the second signal is output from a T2 port of the first bridge, wherein the first signal and the second signal are respectively transmitted to a first power amplifier and a second power amplifier to amplify the signal power of the first signal and the second signal. After the first power amplifier performs power amplification processing on the first signal, the first power amplifier sends the first signal after power amplification to the second bridge, and the first signal enters the second bridge from an A2 port of the second bridge; after the second signal is subjected to power amplification processing by the second power amplifier, the second signal subjected to power amplification is sent to the second bridge, and enters the second bridge from the A3 port of the second bridge, and finally the second bridge combines the first signal and the second signal, and sends the combined signal to be sent to the antenna transceiving terminal from the a1 port, so as to realize the transmission of the signal to be sent.
Optionally, the first power amplifier is a linear power amplifier; the second power amplifier is a linear power amplifier.
Optionally, the amplification gains of the first power amplifier and the second power amplifier are the same.
The first power amplifier and the second power amplifier adopt linear power amplifiers of the same type to meet the change of the same gain and the same phase.
When the phase of the T1 port of the first bridge is 0 degree, as can be seen from fig. 4, the phase of the T3 port, the phase of the a2 port, and the phase of the a1 port in the line on which the first signal is transmitted are 0 degree, and-90 degrees; the phase of the T2 port, the phase of the A3 port and the phase of the A1 port in the line on which the second signal is transmitted are-90 degrees and-90 degrees respectively.
Specifically, the phase difference of the transmission lines of the first signal and the second signal is 0 degree, so that the signal powers of the first signal and the second signal can be directly superimposed, wherein the first signal and the second signal are provided with power amplifiers on the line from the first bridge to the second bridge, the signal to be transmitted by the terminal equipment is increased by 3dB to compensate for the insertion loss generated by the added first bridge and the added second bridge, so that the power of the signals transmitted to the a2 port and the A3 port is the upper limit power of the single-pass line, and finally, the combined signal of the two upper limit signals is output from the a1 port of the second bridge to obtain an additional signal power gain, wherein the ideal gain is 3dB, but the actual gain is 2.8dB due to the 0.2dB insertion loss generated by the added bridge.
2. And (5) receiving and processing the signals.
Specifically, a received signal acquired by the antenna firstly enters the second bridge from an a1 port of the second bridge, the second bridge converts the received signal into a third signal and a fourth signal, and if the third signal is output from an A3 port of the second bridge, the third signal passes through the first splitter, and enters the third bridge from an R2 port of the third bridge; the fourth signal is output from the a2 port of the second bridge, passes through the second splitter, and enters the third bridge from the R3 port of the third bridge, and finally the third and fourth signals are combined by the third bridge, and the combined received signal is output to the transceiving end of the terminal device.
As can be seen from fig. 4, the phase of the a1 port of the second bridge is-90 degrees, the phase of the A3 port in the transmission line of the third signal is-90 degrees, the phase of the R2 port is-90 degrees, and the phase of the R1 port is 0 degree; the phase of the a2 port, the phase of the R3 port, and the phase of the R1 port in the transmission line of the fourth signal are 0 degrees, 0 degree, respectively.
Specifically, the phase difference between the transmission lines of the third signal and the fourth signal is 0 degree, so that the signal powers of the third signal and the fourth signal can be directly superimposed, but since no power amplifier is arranged in the transmission line of the received signal, the insertion loss of 0.4dB is generated in the whole transmission line, and the insertion loss is within the receivable range.
Optionally, the first duplexer is configured to isolate the first signal and the third signal; the second duplexer is used for isolating the second signal and the fourth signal. The first duplexer and the second duplexer are mainly used for isolating a signal to be transmitted from a received signal, i.e. isolating the transmitted signal from the received signal.
The power of the present duplexer is limited, and when the signal power of a signal to be transmitted is 33dBm, if a signal processing device based on a conventional single-set linear power amplifier + duplexer performs signal transmission, and the upper limit of the power of one duplexer is 30dBm, the transmission line at this time cannot meet the power requirement of the signal to be transmitted, and may affect the safety of the duplexer.
Optionally, the power of the combined signal to be transmitted is 2 times of the power of the signal to be transmitted.
Specifically, a signal to be transmitted is converted into a first signal and a second signal, the first signal and the second signal are respectively subjected to signal power amplification by a first power amplifier and a second power amplifier, and then are respectively transmitted to a second electric bridge through a first duplexer and a second duplexer, and finally the first signal and the second signal are combined by the second electric bridge, so that the signal to be transmitted is divided into two paths and then is respectively transmitted from the first splitter and the second splitter, and therefore the power of the combined signal to be transmitted can be 2 times that of the original signal to be transmitted, that is, the power of the signal to be transmitted in the transmission line of the signal processing device provided by the present application can be 2 times that of the upper limit of the power bearing of the duplexer.
Optionally, the first signal and the second signal sent to the received signal output are 180 degrees out of phase.
The transmission line of the signal to be transmitted and the transmission line of the received signal may interfere with each other in the first duplexer and the second duplexer, wherein after the signal to be transmitted enters the duplexer, a situation of transmitting the signal to be transmitted to the received line through the duplexer may occur, that is, the transmission of the signal to be transmitted may interfere with the transmission of the received signal.
For example, if a signal to be transmitted enters a transmission line of a received signal through a duplexer, a first signal in the signal to be transmitted is output from a T3 port of a first bridge, reaches a second duplexer, is transmitted to an R3 port of a third bridge through the second duplexer, and is finally output from an R1 port of the third bridge; the second signal of the signals to be transmitted is output from the T2 port of the first bridge, reaches the first duplexer, is transmitted to the R2 port of the third bridge through the first duplexer, and is finally output from the R1 port of the third bridge, wherein the R1 port of the third bridge is the received signal output terminal.
When the phase of the T1 port of the first bridge is 0 degree, as can be seen from fig. 3, the phase of the T3 port, the phase of the R3 port, and the phase of the R1 port in the transmission line of the first signal are 0 degree, respectively; the phase of the T2 port, the phase of the R2 port and the phase of the R1 port in the line on which the second signal is transmitted are-90 degrees and-90 degrees respectively.
Specifically, the phase difference between the transmission lines for transmitting the first signal and the second signal to the received signal output end (R1 port) is 180 degrees, so that the first signal and the second signal transmitted to the received signal output end can be cancelled out, thereby preventing the signal to be transmitted from being transmitted to the received signal output end, and further improving the transmission effect of the received signal.
The signal processing device provided in this embodiment converts a signal to be transmitted into a first signal and a second signal having a phase difference of 90 degrees through a first bridge, and respectively sends the first signal and the second signal to a first power amplifier and a second power amplifier for power amplification, the first power amplifier amplifies the first signal and sends the amplified first signal to the second bridge, the second power amplifier amplifies the second signal and sends the amplified second signal to the second bridge, the second bridge combines the first signal and the second signal to obtain a combined signal to be transmitted, and sends the combined signal to be transmitted through an antenna, thus, the signal processing device enables the two signals to be amplified by the first power amplifier and the second power amplifier respectively, and then combines and outputs the two signals through the second bridge, the extra signal power gain is obtained, the technical problem that the transmitting power of the communication signal in the prior art is low is solved, and the amplification performance of the mobile phone to the communication signal in the prior art is improved.
Finally, it should be noted that: the above embodiments are only used for illustrating the technical solutions of the present application, and not for limiting the same; although the present application has been described in detail with reference to the foregoing embodiments, it should be understood by those of ordinary skill in the art that: the technical solutions described in the foregoing embodiments may still be modified, or some or all of the technical features may be equivalently replaced; and the modifications or the substitutions do not make the essence of the corresponding technical solutions depart from the scope of the technical solutions of the embodiments of the present application.
