When performing some accuracy testing on the matrix creator using the ODAS software I noticed that above 65 degrees the software latched onto this very quiet noise (potentially not from a physical sou…

Hi,
In the MUSIC code provided there is no data file available. Therefore I would like to know what is the data cube size of the data in terms of samples , chirps and receivers. Is there any preproc…

Hi @jpt13653903
I would like to know what algorithms are used in industry for FMCW beat frequency extraction. So far I believe CFAR is a common method, and Im wondering if the root MUSIC algorithm p…

您好,关于snapshots的问题想请教一下,在实际落地中,其中我们比较关注DOA的灵敏度的,论文中snapshots都是20起步,相当于计算协方差矩阵用的是20帧的信号计算的,这是非因果的,但是如果实际中采用当前帧+历史帧来计算的话,当遇到声源位置变化,协方差矩阵也是不稳定的,所以就此问题,论文中的方案有没有可能实现frame by frame的效果?

Two signal sources:
s = sqrt(sVar)*randn(N, p).*exp(1i*(2*pi*fc*repmat([1:p]/fs, N, 1)));
s = sqrt(sVar)*exp(1i*(2*pi*fc*repmat([1:p]/fs, N, 1)));

I have generated a large set of audio using Pyroomacoustics for room simulation, employing a circular microphone array and a single sound source.
I have successfully trained and tested a CRNN (Conv…
