1 Overview The idea of implementing DPSK modulation on the AD9361 is as follows: first verify the spectrum after DPSK modulation in Matlab, then use a pseudo-random sequence as the original data in the FPGA, and send it to the AD9361 after upsampling, shape filtering, and the AD9361 completes the IQ modulated and ultimately...
Research and design of shaped filters
1 Overview In the process of developing SDR products using the AD9361, in order to compress the spectrum of the digital baseband signal within a certain bandwidth, the shaping filter is obviously an indispensable component. This article gives the design process of the shaping filter, which is not only applicable to the AD9361 ,...
