摘要 根据目前常见的几种发射机结构,针对TETRA数字集群通信系统提出发射机指标,设计了一种数字中频发射机。该发射机可以实现多载波信号宽带发射,并且通过采用数字预失真(DPD)技术大大降低对发射机射频模块和功率放大器的要求。 TA Multi-cartier Transmitter is designed based on TETRA digital Trunk communication system, Digital Pre-distortion Technology is implemented in the transmitter to compensate for the non-ideal behavior of PAs near saturation, thus lower Pas requirements.
