Possibly your homework over XMAS could start here > DOCSIS 3.0 Tutorial - The eQAM

Not forgetting CM-SP-MULPIv3.0-I16 or I15 if more publically available (euroDOCSIS/CableLabs) standard and possibly DOCSIS DRFI specs….
Noise robustness facilitated by interleave (at expense of increased latency) is also a factor in why MPEG transport overhead likely to still be retained..mixed in with DOCSIS QOS (not the same as IP/TCP QOS!) etc….

Have fun digesting that lot! - will look forward to your review…
