Detailed Description

Waveform generator class implementation.

Waveform generator.

This is a waveform generator which contains a symbol generator and pulseshaper.

Example

param.M                 = 4;
param.modulationFormat  = 'QAM';
param.samplesPerSymbol  = 16;
param.pulseShape        = 'rrc';
param.rollOff           = 0.2;
wg      = WaveformGenerator_v1(param);
sigOut  = wg.traverse();

Constructor & Destructor Documentation

function WaveformGenerator_v1::WaveformGenerator_v1

(

in

param

)

Class constructor.

Constructs an object of type WaveformGenerator_v1. It also constructs a SymbolGenerator_v1 and a PulseShaper_v1

Parameters

param.nOutputs	Number of outputs
param.M	Modulation order
param.L	Output sequence length [symbols].
param.PRBSOrder	Polynomial order (any integer 2-23; 27, 31)
param.modulationFormat	Modulation format
param.M	Modulation order
param.N	Number of Modes (or polarizations)
param.samplesPerSymbol	It is the desired output number of samples per symbol.
param.symbolRate	You are able to define a symbol rate for your signal here. The output sample frequency will be define as symbolRate*samplesPerSymbol.
param.pulseShape	Choose among 'rc', 'rrc', 'rz33', 'rz50', 'rz67', 'nrz' or 'custom';
param.filterCoeffs	You should define this as a vector if you chose 'custom' 'pulseShape'.
param.filterSymbolLength	You should define a symbol length for 'rc' or 'rrc' filters. The default value is 202.
param.rollOff	The Roll-Off factor. You should define this value if you are using 'rc' or 'rrc' shapings. Usually, this number varies from 0 to 1.

Return values

obj	An instance of the class WaveformGenerator_v1
