a) Mobile industry opted to use PSK (phase shift keying) over FSK (frequency shift keying). Explain the benefits of PSK over FSK. b) Mobile phones are using quadruple PSK or higher order(s) of PSK. Discuss their throughput capability with a case example of the latest model. c) Explain the differences between diffraction and refraction in electromagnetic wave propagations.

. A continuously operating coherent Binary Phase Shift Keying (BPSK) system is made by an engineer. He claims that it is having an average error probability of 10-5. The system produced 1000 errors in a day when tested with a data rate of 1000 bits/s and the single-sided noise power spectral density is No=10-10 W/Hz. He also claim that the system is capable of maintaining the error rate even if the received power is as low as 10-6 W. Do...

A continuously operating coherent Binary Phase Shift Keying (BPSK) system is made by an engineer. He claims that it is having an average error probability of 10-5. The system produced 1000 errors in a day when tested with a data rate of 500 bits/s and the single-sided noise power spectral density is No=10-10 W/Hz. He also claim that the system is capable of maintaining the error rate even if the received power is as low as 10-6 W. Do you...
