Do we have to insert the DC null in OFDM when using RF direct sampling ADC architecture?
Started by 4 years ago●17 replies●latest reply 2 years ago●769 viewsGenerally, DC Nulls are added in OFDM because zero-IF receivers don't pass the DC component. But what if I use an RF direct sampling architecture? Will there be...
Hi guys, I'm doing some research work on emulating tube amps digitally and I'd appreciate any help you might be able to give me. I was looking into the Wiener-Hammerstein...
Very efficient (or parallel) Eigen solution for complex symmetric Matrix
Started by 2 years ago●10 replies●latest reply 2 years ago●186 viewsI have a matrix that is complex but truly symmetric (not conjugate symmetric).I'm trying to find a reference that will help me build an extremely efficient implementation...
In the late 90s I learned about wavelets as the "big new thing" that would replace the Fourier transform. I could be mistaken, but I don't think that has come to...

Optimal Cascaded FIR Decimator design
Started by 2 years ago●5 replies●latest reply 2 years ago●316 viewsI would like to design an FIR filter to decimate a high rate 1 bit signal to a low rate high bit signal. Due to implementation constraints I have fixed filter length...
Dear DSP experts,I have a measured FRF by impact testing and I have computed the IRF by ifft(). Now I want to compute the inverse IRF. I have read many posts in...
