802.11g Forward Error Correction - RF Cafe Forums

RF Cafe Forums closed its virtual doors in late 2012 mainly due to other social media platforms dominating public commenting venues. RF Cafe Forums began sometime around August of 2003 and was quite well-attended for many years. By 2012, Facebook and Twitter were overwhelmingly dominating online personal interaction, and RF Cafe Forums activity dropped off precipitously. Regardless, there are still lots of great posts in the archive that ware worth looking at. Below are the old forum threads, including responses to the original posts.

Hello all,

Does anyone know what type of forward error correction coding is used in 802.11g?

At 54 Mbps, the 802.11g standards documents states a 3/4 coding rate.

Where can I get more information on the coding using for 802.11g? Is it implementation (chipset) specific?

Thanks for any information!

Regards,

Andrew

It's a normal convoluational code at 1/2 rate. other rates are achieved by puncturing data. You can check the 802.11 standards or any digital communication text books for details. The encoder is standard and the decoder is implementation specific.
