Explanations of Some of the Above Parameters

r53

This number is a measure of the quality of fit between the actual leader data, and the "ideal" leader data. The larger this number is, the better the fit.

clock periods per block

This is the number of receiver clock periods per block, based on the slope of the least squares best fit straight line to the measured vs. ideal frequencies of the leader subcarriers.

Results of initial search for framing sequences

The smaller the "min product" the better.

Best min product found

After searching a range of "clock periods per block", around the previous estimate, this number is the best found. It was found using the number listed as the "offset" as an offset to the previous estimate of the number of clock periods per block.

The next line of output states the updated value of the number of clock periods per block, which will be the same as before, if the offset is 0.

Results of best fit straight lines through better points

The final estimate for the number of clock periods per block is listed at the bottom of this table.

Error Correction Mode Determination Weights

The mode with the largest weight is used in the decoding process.
