First, let’s separate the Voss part from the McCartney. The first generates a 1/f distribution of random numbers, with power inversely proportional to frequency—pink noise. McCartney proposed a change that gives a more flat computational load.
A brief overview of Voss:
Start with random number generators, one for each bit in a binary counter. Let’s ...

So let's look at what the author of the article you linked to says further down;
Output samples are on the top row, and are the sum of all the other rows at that time.
Output /---\/---\/---\/---\/---\/---\/---\/---\/---\/---\/---\/---\/---\/---\/---\/---\/---\/---\

@Ben I try to implement your idea and actually the amplitude of the signal is obtained starting from two components in quadrature.
But when i add an external signal, of the same amplitude, to my input the result is an oscillating signal
How can i reject the noise?

I believe you are running into stability issues in an output power control loop design.
See below a diagram of similar power control loops that I have implemented, where for stability reasons any filtering in the loop is minimized and only done with the loop filter itself which is designed for stability. The noise you are trying to filter gets filtered by ...

You are really close! Change your signal and steering vectors to be complex. Specifically for the steering vectors, these coefficients are meant to act as phase shifts. Using a real sinusoid will introduce a phase shift term in the opposite angle direction, which you don't want. Doing this alone you will see an improvement in your pseudospectrum.
In regards ...

Seven years after this question was firstly raised, I run into this confusion similar to @Nicholas Kinar. Here I would like to provide some "unofficial" and "correctness not fully assured" personal perceptual ideas and explanations.
The title of the following statements are exaggerated for better intelligibility.
Forward process of STFT is not really meant ...
