‫No, the eggs scream Mux blog, Gendry, it's the Packards and these Packards are then given to the
‫Constellation Modulator blog, which modulates these packets in the B span.
‫Now, previously, we had used the PSA modulator block for the modulation, but here we are using the
‫Constellation Modulator blog because the Constellation Modulator blog gives us much more flexibility
‫and many options like we can choose.
‫What is the upsampling factor?
‫And here we have chosen the upset factor.
‫As for we can choose that.
‫What is the excess bandwidth?
‫Our pulse whipping factor that we are going to use.
‫And we can also decide whether we are going to use the differential in recording or more.
‫And then we can also decide that what type of constellation are what type of modulation we are going
‫to use.
‫And this constellation type is set is is set here as the constellation object.
‫And the constellation object is defined as a separate block.
‫And when we Double-Click on the Constellation object, then the first parameter that we see it is the
‫constellation type.
‫And if I click on it, I get these options.
‫I can use the BPC constellation or I can use the BP scheme modulation.
‫I can use the cupie Eskimo relation.
‫I can use the differential kupinski modulation.
‫I can use the eight PSC modulation.
‫And I can also use these sixteen when modulation.
‫And on top of that, I can use the variable constellation.
‫And when I said this constellation type as the variable consultation, in that case, I can myself decide
‫that.
‫What are the constellation points and how many are the constellation points that I'm going to use?
‫And what would be the location of those constellation points on the Constellation diagram?
‫That means that I can define my own modulation scheme.
‫So.
‫So using the Constellation type, we decide that how we are going to modulate these packets in the basement
‫as these complex symbols.
