"For a 20MHz LTE system, the used Bandwidth for 1200SCs is 18MHz which means that minimum fs (sampling frequency) must be >= 36Mhz."No, the 18MHz is the bandwidth...

Check Patrick Naylor, his research group, and the dereverberation book.Another researcher in the field: Emanuël Habets.Good luck!
Here's a link to an article back in 1978 by MIT Prof. Alan S. Willsky, one of the authors of the "Oppenheim Signals and Systems" bible:Relationships Between Digital...
The fact that you "get 5 seconds of perfect sound" from the buffered signal demonstrates precisely that the sample rates are well-matched. As your intuition suggested,...

Scaling the LLRs with their corresponding SNR (or CSI - the absolute value matters only when taking into account LLR quantization and saturation in the FEC decoder)...
