Goodmorning to everyone. I was trying to understand the proof of the cross-correlation theorem for the DFT given in the dsprelated website. It defines the cross-correlation between...

I am working on a Python function to perform audio dynamic range compression using an upward compressor (https://en.wikipedia.org/wiki/Dynamic_range_compre...)....

I am trying to build an application which uses Differential BPSK /Differential QPSK modulated on to a chirp signal. (S2C method). The modulation is multiplication...

I am currently doing some research into automatically removing reverb from audio files related to cleaning up speech. Is there any pointers you guys can share?...

Hello all,I'm using an auto-correlation based frequency recovery algorithm in the receiver to extract and correct the carrier frequency offset between the transmitter...

Almost sixty years ago I needed an all-pass recursive digital filter with two outputs, such that the phase difference between the outputs was a very good approximation...

I read nice discussions on this forum about CIC filters and that's why I also joined. I am not expert in DSP. I am programmer and I need to write a CIC filter for...

In one of the papers related to 5G numerology, I read this statement: "Low number of subcarriers is needed for high path loss scenarios because higher number of...

Hello everyone!I successfully designed the wideband frequency hopped OFDM+BPSK system where I use multiple DUCs and DDCs to achieve up and down-conversion to and...

If I send a random series of symbol impulses (+3.0, +1.0, -1.0, -3.0) through a raised cosine filter (alpha = 0.2, 31 taps), the output contains a filtered, delayed...
