Today in TF, during Q&A after cole_3bs_02a_0914, several requests were made to see the TX and RX analog BW assumptions behind TDP (pages 5 and 6) and RX BW Penalty (page 8).

 

The general answer is that RX analog BW is 75% of the Baud rate. Below is a table with the specifics for 10km TDP and RX BW Penalty.

 

Please let us know if we can provide additional clarifications.
