Yes, for sure. That's the property of short training sequence I think.
In SORA and my code we have already saved frequency domain values of the
short training and long training sequence with which we correlate the
incoming samples and look for sharp peaks and then count the peaks.
For my code it comes something like this

The multiplication and addition stuff we do with SSE instructions, so its
pretty fast, but have to compare it with SC based methods !
