| Abstract: | Digital Down-Converter(DDC) is an important part in the digital receivers.The DDC performes to convert the high speed ADC data to a low speed baseband signal by decimating and filtering. The disadvantages of traditional analog receiver are that have narrow system bandwidth, big system volume and less flexibility faults. Simulated and designed a digital intermediate frequency receiver with small volume(only needs a singlechip ) ,flexible configuration and is implemented it with FPGA, by using Matlab Simulink... |
