Utilities Nodes

Locates the first occurrence of the ideal symbol timing instant in the matched filtered input complex waveform and applies phase-continuous resampling to align the first sample of the input complex waveform to the ideal symbol timing instant.

Calculates the full-scale power adjustment and the peak-to-average power ratio (PAPR).

Calculates the maximum possible peak amplitude, after pulse-shape filtering and resampling, of a waveform.

Estimates and corrects sample clock frequency offset, which is the difference between the sample clocks at the D/A converter of the transmitting DUT and digitizer.

Decimates the input complex waveform and returns the decimated output complex waveform. Use this node to decimate the matched filtered waveform at the output of MT Matched Filter to recover the symbols corresponding to the ideal symbol timing location.

Calculates filter coefficients for pulse-shaping and matched filters applied by the digital modulation nodes and demodulation nodes.

Generates an arbitrarily shaped symbol map representing the I/Q constellation points.

Constructs an FSK, PSK, QAM, MSK, PAM, ASK, or CPM synchronization parameters cluster that you can pass to a demodulation node, using an array of either synchronization bits or synchronization numbers.

Calculates parameters for use with modulation and demodulation nodes.

Maps bits to complex valued symbols for PSK, QAM, PAM, ASK, and CPM modulation schemes and frequency deviations for FSK and MSK modulation schemes.

Maps complex valued PSK-, QAM-, PAM-, ASK-, FSK-, MSK-, and CPM-modulated symbols to an output bit stream based on the symbol map that you specify.

Applies specified matched-filter coefficients to the input complex I/Q baseband waveform.

Maps a CPM- or MSK-modulated complex baseband waveform to an output bit stream using maximum likelihood sequence estimation (MLSE).

Packs data to an unsigned or signed integer array.

Generates a sampled continuous-time I/Q baseband waveform from the discrete-valued input symbols by applying a pulse-shaping filter.

Unpacks data to an unsigned or signed integer array.
