+ * This block is designed to search for a sync word by correlation
+ * and uses the results of the correlation to get a time and phase
+ * offset estimate. These estimates are passed downstream as
+ * stream tags for use by follow-on synchronization blocks.
+ *
+ * The sync word is provided as a set of symbols along with a

+ * upsampled symbols that we will receive over-the-air.
+ *
+ * The phase_est tag can be used by downstream blocks to adjust

+ * implemented by the gr::digital::costas_loop_cc block.

+ * The time_est tag can be used to adjust the sampling timing
+ * estimate of any downstream synchronization blocks and is
+ * currently implemented by the gr::digital::pfb_clock_sync_ccf
+ * block.
+ *
+ * The caller must provide a "time_est" and "phase_est" tag
+ * marking delay from the start of the correlated signal segment,
+ * in order to mark the proper point in the sync word for
+ * downstream synchronization blocks. Generally this block cannot
+ * know where the actual sync word symbols are located relative to
+ * "corr_start", given that some modulations have pulses with
+ * intentional ISI. The user should manually examine the primary
+ * output and the "corr_start" tag postition to determine the
+ * required tag delay settings for the particular modulation,
+ * sync word, and downstream blocks used.
+ *
