File Information

This file set includes a top level unsychronized Tx / Rx model and a more detailed synchronized Rx model. The top level model Tx outptut has been tested with a third party reference mil-std-188-110 modem and found to generates compliant waveforms. A variable symbol rate Tx driving the synchronized Rx model was added on 11/21/08.
The Rx model implements the 1200 bps / short (0.6 sec) interleave mode. It is driven by recorded wave files that have varying degrees of timing and carrier errors to test the tracking loops.
The model includes:
1) selectable channel impairments
2) preamble correlation to initiate downstream processing
3) a 20 forward-20 feedback tap Recursive Decision Feedback Equalizer
3) timing recovery loop to track long term clock rate errors
4) carrier recvoery loop to ease the burdon of the equalizer
5) novel timing and phase error detectors
6) received data converted to scrolling text output

This model is very useful. Could the author or someone else give a detailed discussion about the timing and carrier recovery algorithm used in this model?
