Detailed Description

PPG Pulse pattern generator.

Outputs a 2^order - 1 pseudorandom sequence repeated up to total_length bits with Rs symbol rate. If block attribute is set, the unit is set to do block-processing.

Example PRBS sequence generator polynomials

• PRBS7 = x^7 + x^6 + 1
• PRBS15 = x^15 + x^14 + 1
• PRBS23 = x^23 + x^18 + 1
• PRBS31 = x^31 + x^28 + 1

Parameters

param.nOutputs	Number of output sequences. [Default: 1].
param.total_length	Output sequence lenghts [symbols].
param.Rs	Symbol rate
param.levels	Amplitude levels as vector [level0 level1]. Takes precedence respect level0/1
param.level0	Amplitude of high level. [Default: 1].
param.level1	Amplitude of low level. [Default: 0].

Return values

obj	An instance of the class PPG_v1

Member Function Documentation

function PPG_v1::setLevels	(	in	obj,
		in	levels
	)

Set the amplitude levels of the PPG generator.

Parameters

levels

If scalar the value is assigned to level1. If vector the max is assigned to level1 and the min to level0.
