T/CIPR 044-2022 Wireless digital radio transmitter/receiver
Basic Information
Scope
Main technical content: This technology includes an inductive antenna, a radio frequency unit, a baseband processing unit, a human-machine interface unit, and a power supply unit. It adopts digital signal time-division transmission mode, realizes time division into three time slots in a 25KHz bandwidth channel, and synchronizes digital wireless signals with GPS technology to achieve an airborne wireless transmission rate of 64Kbps, thus satisfying the functions of high-speed data and voice transmission simultaneously, and automatic matching and adjustment of adaptive antenna impedance; When the time slot is idle, all three consecutive time slots can transmit or receive. In the time-division full-duplex working mode, these three time slots can share the same channel simultaneously. While communicating by voice, users can also receive data transmission services wirelessly. Within each time slot channel, CSMA competition sharing of channels can improve work efficiency and spectrum utilization, satisfying the functions of high-speed data and two-way voice transmission simultaneously.
