The Discussion of Intermediate Frequency Receiver Using Software Radio-Technology
Yuan Zhao-gan · Information Technology and Informatization · 2006
The input singnal of intermediate frequency reciever is a band-pass signal and the figure must be transformed before being processored,i.e.one real signal is turned into two perpendicular numeric sequences.The transformed digital signal has the total phase and value of the intermediate frequency signal before it is digitalized.How to realize the digital sampling and perpendicular transform of intermediate frequency reciever using software radio-technology is discussed chiefly in this paper.
