pulse2wave

Data pattern waveform from pulse response

Since R2020a

Syntax

W = pulse2wave(P,D,N)

Description

W = pulse2wave(P,D,N) converts the pulse response P into a voltage waveform W, given the symbol pattern D and the number of samples per symbol N.

The function uses a circular convolution technique to project the pulse response onto the data pattern.

Examples

Create Voltage Waveform from Pulse Response

Load the pulse response column matrix from a file.

load('PulseResponseReflective100ps.mat');

Find the pulse response column vector.

P = pulse(:,1) - pulse(1,1);

Create the symbol pattern of PRBS order 5.

data = prbs(5,2^5-1)-0.5;

Calculate and plot the voltage waveform from the pulse response.

waveform = pulse2wave(P,data,SamplesPerSymbol);
t = dt*(0:length(waveform)-1);
figure
plot(t,waveform)
xlabel('Time (Seconds)')
ylabel('Voltage')

Input Arguments

P — Pulse response

column matrix

Input pulse response, specified as a column matrix. The first column contains the primary pulse response and the subsequent columns (if any) contain the crosstalk pulse responses.
