Better yet, at the bit level. + +Of course this is probably all overkill because we would normally expect to have pretty +decent signals. The designers didn't even bother to add any sort of checksum for error checking. + +The random errors injected are also not realistic. Actual noise would probably wipe out the +same bit(s) for all of the slices. + +The protocol specification suggests comparing all 3 transmissions and taking the best 2 out of 3. +I think that would best be left to an external application and we just concentrate on being +a good modem here and providing a result when it is received. + +*/ + + +/*********************************************************************************** + * + * Name: hdlc_rec_bit + * + * Purpose: Extract HDLC frames from a stream of bits. + * + * Inputs: chan - Channel number. + * + * subchan - This allows multiple demodulators per channel. + * + * slice - Allows multiple slicers per demodulator (subchannel). + * + * raw - One bit from the demodulator. + * should be 0 or 1. + * + * is_scrambled - Is the data scrambled? + * + * descram_state - Current descrambler state.

The one thing I disagree with is + * use of the word "swap" because that sounds like two things + * are being exchanged for each other. I would prefer "flip" + * or "invert" to describe changing a bit to the opposite state. + * I took "swap" out of the user-visible messages but left the + * rest of the source code as provided. + * + * Test results: We intentionally use the worst demodulator so there + * is more opportunity to try to fix the frames. + * + * atest -P A -F n 02_Track_2.wav + * + * n description frames sec + * -- ----------- ------ --- + * 0 no attempt 963 40 error-free frames + * 1 invert 1 979 41 16 more + * 2 invert 2 982 42 3 more + * 3 invert 3 982 42 no change + * 4 remove 1 982 43 no change + * 5 remove 2 982 43 no change + * 6 remove 3 982 43 no change + * 7 insert 1 982 45 no change + * 8 insert 2 982 47 no change + * 9 invert two sep 993 178 11 more, some visually obvious errors. + * 10 invert many? 993 190 no change + * 11 remove many 995 190 2 more, need to investigate in detail. + * 12 remove two sep 995 201 no change + * + * Observations: The "insert" and "remove" techniques had no benefit.
