There is an error in the above video when we show the spacing between the OFDM subcarriers. We incorrectly list that as 25 MHz to 50 MHz. That should be 25 kHz to 50 kHz.
The standard deviation of the MER (Modulation Error Ratio) is measured across the OFDM channel. You want a lower standard deviation (preferably less than 2 dB).

Good job, great information and easy to understand delivery
What is the throughput or speed capacity of an OFDM carrier depending on how wide the carrier is also by different profile modulations?
This may provide some answers to that question if you are good with math: volpefirm.com/ofdm-capacity-in-docsis-3-1-and-4-0/
I was wondering if you could explain Standard Deviation in OFDM. Do you want a higher or lower value?
Thanks
