What do coding gains give me?
•
The new DVB-S2 codec (LDPC) allows for some
real-world savings
•
Now that you have a codec with an additional 2.5dB
in coding gain you can “use”
this gain to do quite a
few things
–
You could lower antenna sizes
–
You could use lower cost power amplifiers
–
You could change modulation or FEC and reduce BW
–
You could change modulation or FEC, keep the BW and get
more data through the same size
“pipe”
