I am PhD student doing research in area of Digital Signal Processing, Software Defined Radio, Mobile Networks and Digital Design. My main focus is hardware acceleration of Digital Signal Processing algorithms on hybrid FPGA-CPU architectures (such as Xilinx Zynq SoC).

Hi,I think that your question is really nice but in same time there is a huge set of possible answers. However, I will try to offer suggestions related to array...

Hi All,I am working on my PhD in field of Signal Processing (to be more specific Signal Processing for communications). Based on what people do in research community...
Hi,Your sampling rate is fine.I feel that you are a bit confused with frequency and pahee offset. Phase offset you can perform after you performed frequency offset....
Hi Mukul,I need to ask you one questions before offering any answers:- What is sampling rate of ADC that you are using?Here are further comments:- You can do Hilbert...

Hello Saharan, Sorry for late reply. In that example both mapping to quadrature components and frequency shift to RF happens in same time. You would need to use...
