Re: [Freetel-codec2] LoRa Modulation

nice Mark. yeah checksums/CRC with LDPC is redundant.... you get your CRC for free of course... agreed on use of CS for uncoded reference. I am usually using shorter blocks, with low code rates (1/5 etc). My stuff is all based around David Mackay's work. cheers On 12/03/2017 7:53 PM, Mark Jessop wrote: Tone spacing is around 120 kHz. Occupied bandwidth is a lot more :-) The code is a (2064,516) code (r=4/5). 2064 being 256 bytes of packet data + 2 byte checksum. Yes, I could probably get rid of the checksum, it's still there for legacy reasons (and so we could compare PER of coded and uncoded). - Mark VK5QI On Sun, Mar 12, 2017 at 6:26 PM, glen english <g...@cortexrf.com.au> wrote: Stuart, nice work. what block size is the LDPC code for said project ?
