PSK synchronization parameters
Synchronization parameters to pass to the demodulation node.
The node always uses normal PSK when creating the PSK synchronization parameters cluster, even if the PSK type specified when creating the PSK synchronization parameters cluster is shifted or offset. This supplies an absolute phase reference for MT Demodulate PSK during the process of symbol synchronization.
If the synchronization parameter passed to the demodulation node is left empty, the constellation of the demodulated waveform has a 90° carrier phase ambiguity for two-dimensional modulation schemes (QAM, QPSK, and higher order PSK) and a 180° carrier phase ambiguity for one-dimensional modulation schemes (PAM/ASK/BPSK).
expected sync location
The expected location of the first symbol of the sync sequence.
This value is an index to the input complex waveform. A value of -1 searches the entire input complex waveform and ignores the sync location uncertainty parameter.
The mapped symbol array from the specified synchronization bits or synchronization numbers.
sync location uncertainty
Number of symbols before or after the expected sync location where the first symbol of the sync sequence may be located. The node ignores this parameter if the expected sync location parameter is set to -1.
Distance that the sync sequence is indented into the information block.
The distance is the number of demodulated symbols preceding the sync sequence. For example, a value of 10 indicates that the output bit stream consists of 10 data symbols, followed by the sync sequence, followed by the remaining data symbols.
