Hello students, we are required to design and perform a wireless communication project by using matlab software and there are 9 type of moderation techniques used in this project.
00:16
So we have ask which is amplitude shift keying, then frequency shift keying, phase shift keying, differential phase shift keying.
00:28
So we can we differ for differential phase shift keying is the question here.
00:35
So differential phase shift keying is what we are supposed to choose as of the question.
00:42
So we are choosing that.
00:45
Now we need to use the simulation of differential phase shift keying, modulation and demodulation.
00:54
So we can assume that an ideal communication channel without any noise, no noise or distortion is there.
01:04
So in real world, this will be this will not be the case.
01:11
There will be channel impairments and there will be noise models added to this thing.
01:17
So let's write down the matlab codes.
01:20
First we need to define the parameters parameters.
01:24
So bit stream length or let bit stream length will be equal to 100.
01:35
So this corresponds to the length of the bit stream.
01:37
The data will be equal to random random random 0 to 1, 1 bit stream length length.
01:58
So this will generate a random bit stream.
02:01
Now we can use dsp modulation.
02:04
So modulated signal modulated signal ms will be equal to dpsk mode data comma 2.
02:15
So this is the 2 for binary dspk.
02:19
We have put down 2 as binary dpsk.
02:23
Now we can we have the wireless channel ready.
02:29
So ideally no channel impairments or noise...
