Other Possibilities for DNRZ Codes in OQPSK Mode 3.3.4.2.2
Next table summarizes the 24 possibilities for DNRZ codes in OQPSK Mode:
DOQPSK configuration 3.3.4.2.3
Using the example of the most common DOQPSK code, and its decoding look-up table:
In 0 0 1 1 1 1 0 0 0 0 1 1 1 1 0 0
1 0 0 1 1 0 0 1 1 0 0 1 1 0 0 1
To select this code, set Cortex HDR ICD parameter to 1 (code number in the left-hand column of the
above table) or enter the DNRZ code value (0x3C3C9999) as defined in the above decoding table).
Selection of the other codes follows the same rule.
