The communication architecture according to claim 2, wherein the process control module is configured to: Receive the remote control command given by the MAC module and enter the initial state; detection system response mode; If the system response mode is a full-duplex initiation mode, enter state 1, control the modulation unit to send the single carrier of 1s and the idle sequence of 384bit in turn; form the SPDU frame with the input parameters of the MAC module, send it into the modulation unit and send it; Turn off the transmitter after sending the 64bit tail sequence; control the timer to start, when the timer reaches the preset time T2, if the call response command returned by the receiving end is invalid, the control timer is cleared, enters state 2, and the timer is cleared 0; set the transmitter parameters to the default rate, frequency and encoding mode in the full-duplex initiation state, and jump to state 1 after the setting is completed; if the call response command returned by the receiving end is valid, set the demodulation unit itself Relevant parameters, the timer is cleared to 0, and enters state 3; If the system response mode is full-duplex response mode, enter state 0, when the SPDU parameters of the receiving processing module are successfully received, a corresponding call response frame is generated, added to the urgent sending sequence, and the demodulation unit service is set Frequency point, rate and encoding method; if the bit is synchronously locked, enter state 3; In state 3, set the transmitting unit parameters and receiving unit parameters to the frequency point, rate and coding mode of the corresponding service, control the modulation unit to start, and realize switching control after sending a 1s single carrier and 384 idle sequences. 6. The communication architecture according to claim 5, wherein the process control module is also used for: When switching control, switch the state according to the mode indicated by the remote control command given by the MAC module; When the mode indicated by the remote control command is a non-adaptive mode, enter state 4, if the flow control command of the modulation unit is 0, the request to the ARQ module can be set to 1, so that the ARQ module receives the enable Then output a full frame of urgent frame data whose priority is higher than that of the sequential frame; when it is detected that the output enable of the ARQ module is 1, the number enable is set to 0, the frame length M1 is extracted, and the entire frame is output to the modulation unit ;When it is detected that the output of the ARQ module is enabled to be 0, it is detected whether the lock is lost, whether the local no data is valid and whether the remote no data is valid; wherein, if the lock is lost, reset the modulation unit and the demodulation unit and return to the initial state ; If the local no data and remote no data are effective simultaneously, reset the modulation unit and the demodulation unit, and return to the initial state; otherwise, proceed to state 5; under state 5, the control counter starts counting, when the count reaches the preset value When M1, the counter is cleared to 0 and switching control is realized; When the mode indicated by the remote control instruction is the adaptive mode, and the process control module receives the SPDU for switching the parameters of the other party’s transmitter, it enters state 6, and sends out the SPDU for switching the parameters of the other party’s transmitter. Send out any information again, and enter state 7; in state 7, the control timer starts, and when the timer reaches the preset time T3, if the bit synchronization lockout command sent by the receiving processing module is still not received, then return to state 6. The number of times counter is recorded as 1. When the number of times counter is recorded as 3, the adaptive switching is ended and the switching control is realized; if an out-of-lock instruction is received from the receiving processing module, the number of times counter is cleared to 0, the timer is cleared to 0, and enters State 8; in state 8, set the demodulation unit to the new service parameters, and start timing, when the timer reaches the preset time T4, check the lock-out instruction, if it is still not locked, end the adaptive switching, reset the modulation unit and The demodulation unit returns to the initial state; if locked, end the adaptive switching, return to state 4, and start sending data; When the mode indicated by the remote control instruction is the adaptive mode, and the process control module receives the SPDU for switching the parameters of the local transmitter, it enters state 9, sets the modulation unit to the new service parameter, ends the adaptive switching, and enters state 4.
