Hello Andy and all,
TKS for the reception text.
Unproto ALE is a FEC mode as each character is Golay coded. But contrary to ARQ
it is not error-free...
The sensitivity is S/N=-4 dB contrary to FAE (or DBM) ARQ which is -6,5 dB
(down to -8.5 dB), this for two reasons:
* if an error is detected in the CRC of an ARQ frame (DMB, DTM or FAE), the
frame is repeated,
* in the message part of the DBM or FAE frame, you can use the maximum Golay
correction (3 errors).
In a standard ALE message, you are raesonably limited to one correction. With
more than one correction, you are going to decode random characters.
