upconverter 中文意思是什麼
upconverter
解釋
上變頻器增頻變頻器-
To meet the waveform requirements, dds + multiplier + upconverter was used to realize the c - band fmcw frequency source
為滿足波形參數要求，本文設計了dds +倍頻+上變頻的c波段三角形調頻連續波頻率源。 -
Secondly, we used the dsp assembly language to perform the carrier phase tracking based on a digital processing system. this system is designed according to the idea of software radio. this digital processing system realized the intermediate frequency digitalization. with the diverse configuration of the digital upconverter and digital downconverter in this system, it can carry through many signal modulation modes. and because the carrier phase trac king is performed using software in dsp, it brings great convenience to this system and makes this system available in many digital communication systems
在該數字處理平臺上可通過加載不同的軟體對平臺中的數字上下變頻器進行靈活的配置以實現不同的數字調制解調制度，通過將載波的相位跟蹤工作放在dsp軟體中進行帶來了很大的靈活性，能夠適用於當前許多種數字通信系統。
