It's been a few months since the launch of the new forums.  Here are a few thoughts. The thumbsup and beer buttons    If there is one thing that could have a...

I'm trying to find material for design and implementation of ODFM waveform. I know the very basics. I'm not that familiar with, with the receive portion. Examples...

Hello,I would like to understand the process of 'near IQ' sampling. I might be using incorrect terminology (so please correct me if this is true) but the idea of...

I'm trying to analyze a over the air RF capture. I have a RAW IQ data samples but the sample rate is 30.72Msps. The bandwidth occupied by the signal is about 10MHz...

Hello everyoneI'm trying to implement an IIR filter called "Shelving filter" on an embedded device. After implementation, the filter seem to function almost as expected,...

I have complications implementing the range-azimuth with the 2D Music algorithm. I have used the URA-azimuth to find the reflected signal by the elevation angles...

Hi all,I have been doing some experiments with SDR boards(Xilinx ZCU111 Board),I encountered a weird phenomenon,but I cannot explain with my knowledge of the DSP/radio...

I already posted my question on stackoverflow but hopefully I can get some comments/answers from DSP experts contributing to this forum too:For regular FIR filters...

Hi all,I'm simulating 65 MHz RF data and sampled that sinewave with 120MHz fs. Passed that signal with two stage decimation filter. My final stage filter output...

Hello,I am sampling, at 192 Khz each channel, a radio signal with a IQ mixer and 2 ADC's. I combine the values into complex numbers. Literature tells that using...
