Base Station Receiver Design of TETRA Digital Trunking System
Xuezhi Tan · Dianzi qijian · 2006
Aiming at request of private mobile radio,technology requirement of base station receiver based on TETRA protocol is analyzed,and two intermediate frequency superheterodyne structure is selected.Noise quotiety and plus are distributed to each part.Finally satisfied integrate circuit devices in miniature are selected to accomplish circuit design and implement.The noise quotiely is 3.4 dB,co-channel and adjacent interference are small,and it achieves the requirement of digital trunking experiment system.
