What is the difference between encoding the information in polarisation of photons and encoding in phaseby performing phase modulation?

In quantum Communication we encode information in polarisation state. But this can also be done performing phase modulation. And infact, we can go to more number of states using phase modulation....

What is the significance of lambert's mode number(also known as Lambertian Order of emission) of an LED in Visible Light Communication?

Light from an LED has a Lambertian radiation pattern, and the radiation pattern depends on the Lambertian order. And Lambert's mode number depends on the semi-angle of the LED. I have a clear...

What should be the length of cyclic prefix to be added in OFDM?

In OFDM, First we modulate our message signal and then we take the IFFT of that signal to load the message on subcarrirers. And after that the cyclic prefix is added to combat the frequency...
