getMatchedFilter

System object: phased.PhaseCodedWaveform
Package: phased

Matched filter coefficients for waveform

Syntax

Coeff = getMatchedFilter(H)

Description

Coeff = getMatchedFilter(H) returns the matched filter coefficients for the phase-coded waveform object, H. Coeff is a column vector.

Input Arguments

H

Phase-coded waveform object.

Output Arguments

Coeff

Column vector containing coefficients of the matched filter for H.

Examples

Get the matched filter coefficients for a phase-coded pulse waveform that uses the Zadoff-Chu code.

hwav = phased.PhaseCodedWaveform('Code','Zadoff-Chu',...
    'ChipWidth',1e-6,'NumChips',16,...
    'OutputFormat','Pulses','NumPulses',2);
coeff = getMatchedFilter(hwav);
stem(real(coeff));
