Modulation:
π
/4 DQPSK with an alpha = 0.4 root raised cosine filtered
Symbol rate: 256 ksymbols/s.
Transmission burst: Each burst has a 500 s nominal duration with 20 dB of raised cosine shaping of 8 s
duration at the beginning and the end of the burst. A maximum of three bursts occur in each 5 ms period, but
consecutive bursts are separated by a minimum interval of 1 ms.
Duty cycle: 30%, 3 bursts per 5 ms frame with a minimum interval of 1 ms between bursts.
The modulation signal has a peak to mean envelope ratio of 3.1 dB.
Values of S11 and S22 with match as realized on application board.
