PRACH Detection - combine_symbol loop bug?

RafalArciszewski opened this issue · 1 comments

Hello srsRAN Team

Could you explain what combine_symbols variable means? It is used in upper phy PRACH detection function. On the one hand there is following comment in the prach_detector class:

From this comment I conclude that when combine_symbols is set to true then PRACH detector will iterate over all prach ports and prach symbols and combine them in one symbol which will be processed further.

On the other hand the comment in detect function and in the loop itself suggest something else. When combine_symbols is true only the first symbol is taken. I will iterate over all symbols when combine_symbols is false.

Is it a bug in the loop?

Is this variable configurable? I couldn't find it in configuration files.

Regards,

sorry for bothering, I have figured it out.
