Base on above several topics, the thesis categorizes transmitter system in signal conversion, system clock method, signaling method. 最后是根据以上的分析,在信号编码、系统时钟、信道驱动器上对发送器系统进行了分类比较。
The hardware of the transmitter includes the control circuit of DSP, the interface circuit of GPS and DSP, the DDS and clock circuit, the filter circuit, and the power amplifier circuit. 发射机的硬件部分包括DSP控制电路、GPS与DSP接口电路、DDS电路、时钟电路、滤波电路、功率放大电路。
In the widely used serial communication, the data will be transmitted from transmitter to the receiver without a synchronous clock. 在目前广泛应用的串行数据通信中,数据从发送端传输到接收端通常没有同步时钟的伴随。
In order to speed up the recovery clock locking to the transmitter 'clock, design clock fast lock and slow lock to dynamically control the recovery of local clock. 设计中为了加快恢复时钟锁定于发送端时钟的速度,设置了时钟快锁和慢锁。
