This paper discusses key technology in the digital intermediate frequency receiver with wide band based on software radio,including down-converter on condition of band-pass-sampling,digital down-converter,multi-rate digital signal processing,band-pass signal decimating,and achieves software system simulation based on under-sampling.As what is concluded from the above that it is practicable to design the digital intermediate frequency receiver with wide band at present.
