constellation

System object: comm.OQPSKModulator
Package: comm

Calculate or plot ideal signal constellation

Syntax

y = constellation(h)
constellation(h)

Description

y = constellation(h) returns the numerical values of the constellation.

constellation(h) generates a constellation plot for the object.

Examples

Calculate OQPSK Modulator Reference Constellation Values

Create an OQPSK Modulator System object and calculate its reference constellation values.

Create a comm.OQPSKModulator System object.

h = comm.OQPSKModulator;

Calculate and display the reference constellation values by using the constellation function.

refC = constellation(h)
refC =

   0.7071 + 0.7071i
  -0.7071 + 0.7071i
  -0.7071 - 0.7071i
   0.7071 - 0.7071i

Plot OQPSK Modulator Reference Constellation Values

Create an OQPSK Modulator System object and plot its reference constellation.

Create a comm.OQPSKModulator System object.

h = comm.OQPSKModulator;

Plot the reference constellation by using the constellation function.
