自动识别系统电台的卞要功能是在接收状态将接收到的射频信号解调成高斯最小频移键控(GMSI})比特流以供信号处理板使用 而在发射状态则将来自处理板的9.6 kbps的GMSI}比特流调制成适合发射的射频信号并发射。木电台使用半双工方式工作，共用一副大线，其中发射通路只有一个通道，但可通过微处理器改变调制芯片LMX1501的内部设置数以产生两个频率，然后再经过卜变频得到中心频率分别为162.025 MHz和161.975 MHz的发射信号 木电台的接收则分为二路，其解调芯片都是用TA31136来实现的，其中两路用来接收中心频率分别为162.025 MHz和161.975 MHz信号，另一路用来接收数字呼n}}信号，中心频率为156.025 MHz。二个通路的结构、工作原理和使用的器件都基木相同。

-Bian automatic identification system stations to function in the receiving state will receive the RF signal demodulation into a Gaussian Minimum Shift Keying (GMSI)) bit stream for the signal processing board used　while the state will launch from the processing board The GMSI) of 9.6 kbps bit stream into a modulated RF signals suitable for launch and launch. Wood work station using the half-duplex mode, sharing one big line, which launched only one channel path, but can be modulated by changing the microprocessor chip LMX1501 number of internal settings to produce two frequencies, and then get through the BU center frequency of inverter for 162.025 MHz and 161.975 MHz transmit signal　wooden radio receiver is split Road, its demodulator chips are used to achieve TA31136, in which two-way center frequencies were used to receive 162.025 MHz and 161.975 MHz signal, the other all the way to receive digital calls n)) signal, the center frequency of 156.025 MHz. 2 channel structure, working
