Joe Taylor 14385611be Code cleanup related to "bcontest". Auto-seq now OK for new NA VHF Contest messages. 2018-07-11 10:13:42 -04:00
Joe Taylor d95d2df5b6 Old-style "NA VHF Contest" mode removed from all Fortran routines. 2018-07-10 15:09:42 -04:00
Steve Franke 622ed4a3ab Working toward whole-hog switchover to new LDPC code with 77 bit messages in MSK144. 2018-07-07 09:44:52 -05:00
Steve Franke acb25dd13c Merge in K1JT's 77bit message code. 2018-06-30 15:47:33 -05:00
Steve Franke 1aeaa1715b Fix up ldpcsim144 for comparisons with ldpcsim128_90. 2018-06-14 09:59:49 -05:00
Steve Franke 9b63fe6ac7 Fix a bug in ldpcsim144 so that nerrhisto.dat is calculated and printed. 2018-06-12 16:00:06 -05:00
Joe Taylor 1022a55665 Somewhat pedantic, but better not to call "hash code" a CRC.

Bill Somerville dd1362b69a Rationalize NA contest mode 
Generic message packing and unpacking routines now understand antipode
grid contest messages.  These messages  are now recognized as standard
messages in  message response processing and  dealt with appropriately
when contest mode is selected and applicable (currently FT8 and MSK144
only).

Steven Franke 827d7173fe Fix an error in SNR_2500 scaling and add calculation of probability of decode vs number of hard errors.

Steven Franke fa45380b51 Bring ldpcsim40.f90 up to date and add coherent averaging option to both ldpcsim144 and ldpcsim40. These routines simulate only the performance of the code and the hash/CRC.

Steven Franke ca19e977c0 Add early termination code to the msk144 long-message decoder. Remove references to Radford Neal's ldpc code, which served us well but is no longer needed.

Steven Franke 7ba75b79c9 Add routines to decode msk40 and msk144 messages using log-domain belief propagation. Also add new routines to test msk144/msk40 encoding and decoding.
