! Decode WSPR-LF data read from *.c5 or *.wav files.
|

|
||||
! WSPR-LF is a potential WSPR-like mode intended for use at LF and MF.
|
||||
! It uses an LDPC (300,60) code, OQPSK modulation, and 5 minute T/R sequences.
|
||||
|
||||
! Reception and Demodulation algorithm:
|
||||
! 1. Compute coarse spectrum; find fc1 = approx carrier freq
|
||||
! 2. Mix from fc1 to 0; LPF at +/- 0.75*R
|
||||
! 3. Square, FFT; find peaks near -R/2 and +R/2 to get fc2
|
||||
! 4. Mix from fc2 to 0
|
||||
! 5. Fit cb13 (central part of csync) to c -> lag, phase
|
||||
! 6. Fit complex ploynomial for channel equalization
|
||||
! 7. Get soft bits from equalized data
|
||||
|
||||
! Still to do: find and decode more than one signal in the specified passband.
