I have been looking into using LDPC's in some of my projects and have had some questions come up. Currently my structure looks something like this:
I am then able to have hardware wake when it sees the preamble, read the length byte, and even check CRC for me before my processor has to handle the packet at all. This takes a lot of load off of processing time as well as code writing time.
What I am wondering is if there is any hardware out there that can use LDPC or any other correction code in a similar manner to what I am currently doing. Preferably it would be included with the wireless module, especially if it is able to do some soft decoding, but I am starting to think there isn't anything out there that does that currently. Because of this I am also open to "in-line" hardware that can assist with this.
So, know of anything?
