The present embodiment also provides one while alloing user to realize the intercommunication function of mobile phone based on intercommunication accessory
The full-duplex transceiver system of kind, as shown in Figure 10, the present embodiment is based on digital wireless communication to the full duplex time slot that the present embodiment is provided
The concept of the 30ms time slots of technical standard order, the time slot 1 and time slot of two autonomous workings by boundary definition of 30ms time slots
2, full duplex digital intercom method is applied sends signal using a time slot, and next adjacent time-slots receive double time slot time divisions of signal
The mode of multiplexing；In actual applications, the time slot length of full duplex time slot can carry out any set according to technology development.
Transceiving data, sets up 30ms time slots in a full-duplex mode when sender actively sends, and recipient receives synchronization
After frame, 30ms time slots are set up according to the synchronous head received, so when the signal of sender's reality output is due to making radio-frequency channel
Into during delay, the time slot that recipient sets up according to the synchronous header received can produce deviation, just have to adjustment.
Figure 11 describe to send square signal is not calibrated and calibration after internal 30ms time slots and aerial DMR (digital radio leads to
Letter) signal, wherein,
Clock register of the 30ms- time slots in intercommunication module is produced, and transmission is produced for the interrupt location in intercommunication module
Interrupt signal (TX interruptions) and reception interrupt signal (RX interruptions)；Send interrupt signal triggering radio frequency unit and enter sending mode,
It is corresponding, receive interrupt signal triggering radio frequency unit and enter reception pattern；
Interrupt location produces TX and interrupted and RX interruptions, the radio frequency unit in intercommunication module is transferred to, because radio frequency unit is matched somebody with somebody
Putting radio frequency needs the long period, in order that data signal can be sent in the sending time slots of 30ms- time slots by obtaining radio frequency unit, needs
TX is interrupted and shifted to an earlier date, △ t1 are interrupted and inside 30ms Timer intervals to send, it is more than based on regulation register
Adjust stepping, it should unlimited to configure the time that radio frequency needs close to radio frequency unit, posted by the Reg0x12 for configuring C5000 chips
The bit0-5 (stepping 100us) of storage can adjust △ t1 sizes；
Theoretical output signals are the radio frequencies in the case of the parameters such as equipment processing delay, channel propagation delay are not considered
Unit is sent to aerial signal；But, because chip internal and radio-frequency channel can have delay, if without calibration, in fact
As shown in figure 11, real output signal differs △ t2, △ t2 with theoretical output signals and is designated as theoretical output signals border output signal
With the time interval for being effectively outputed to aerial signal, in actual applications, △ t2 size computational methods can use oscillograph to touch
Hair pattern, the Tx_inter interrupt pins of a probe pen point sender, the detection RSSI (Received of another probe pen point recipient
Signal Strength Indication, received signal strength indicator) pin, calculate time interval T, time interval T=
△ t1+ △ t2, and then on the basis of known to △ t1, calculate △ t2 values；
In order that it is identical with theoretical output signals as far as possible, it is necessary to which school is adjusted to △ t2 values to obtain real output signal
Standard, as shown in figure 11, output signal and the difference of theoretical output signals are △ t3 after calibration, then adjusted value △ T=△ t2- △
t3；In actual applications, it is necessary to which bit0-4 (stepping 100us) the regulation △ t2 of the Reg0x2e registers by configuring C5000 are big
It is small, for example configure output signal and theory signal interval △ t3 after Reg0x2e, calibration and be less than regulation stepping 100us, approximation theory
Output signal.
△ t1, △ t2, △ t3 involved by Figure 11 are the signal adjusting parameter that above-described embodiment is related to, now, according to
Signal adjusting parameter, adjust according to full duplex time slot produce receptions interrupt signal and transmission interrupt signal interruption position and
Digital intercom signal pre-set time parameter to be sent is：Interrupt location is produced in TX interruptions and RX interruptions according to 30ms time slots
Interruption position move forward △ t1, digital intercom signal pre-set time parameter to be sent be △ T=△ t2- △ t3.
A kind of full-duplex transceiver system is present embodiments provided, realizes that simply cost is low.
