Design and Implementation of a HF RF Digitized Receiver
Yang Xue-fei · Telecommunication Engineering · 2009
To overcome the the drawbacks of high complexity and poor flexibility in traditional IF receivers,a novel short-wave(HF) RF receiver is developed,which mainly consists of A/D,DDC,DSP,D/A and CPLD,and realizes the RF-digitalization of HF signals.The design of the receiver is introduced and the receiver performance using AM signal,CW signal and ISB signal is tested.The SND of the output signals can achieve 12 dB when the input level ranges-103~0 dB.
