* \brief Frequency Lock Loop using band-edge filters
*
* \ingroup general
+ *
+ * The frequency lock loop derives a band-edge filter that covers the upper and lower bandwidths
+ * of a digitally-modulated signal. The bandwidth range is determined by the excess bandwidth
+ * (e.g., rolloff factor) of the modulated signal. The placement in frequency of the band-edges
+ * is determined by the oversampling ratio (number of samples per symbol) and the excess bandwidth.
+ * The size of the filters should be fairly large so as to average over a number of symbols.
+ * The FLL works by calculating the power in both the upper and lower bands and comparing them. The
+ * difference in power between the filters is proportional to the frequency offset.
+ *
+ * In theory, the band-edge filter is the derivative of the matched filter in frequency,
+ * (H_be(f) = \frac{H(f)}{df}. In practice, this comes down to a quarter sine wave at the point
+ * of the matched filter's rolloff (if it's a raised-cosine, the derivative of a cosine is a sine).
+ * Extend this sine by another quarter wave to make a half wave around the band-edges is equivalent
+ * in time to the sum of two sinc functions. The baseband filter fot the band edges is therefore
+ * derived from this sum of sincs. The band edge filters are then just the baseband signal
+ * modulated to the correct place in frequency. All of these calculations are done in the
+ * 'design_filter' function.
+ *
+ * Note: We use FIR filters here because the filters have to have a flat phase response over the
+ * entire frequency range to allow their comparisons to be valid.
