Coherent Binary PSK and Carrier Synchronization

Coherent Binary Phase Shift Keying (PSK) is a modulation technique that uses the phase of the carrier wave to transmit digital signals. The carrier wave's phase is shifted by 180 degrees to represent two different digital symbols - 0 and 1. The receiver needs to synchronize with the carrier signal to correctly decode the received signal.

Carrier Synchronization

Carrier synchronization is the process of aligning the received carrier wave's phase with the local oscillator's phase at the receiver. Carrier synchronization is required to avoid phase ambiguity and correctly demodulate the received signal.

Bandwidth Efficiency

Bandwidth efficiency is the ratio of the data rate to the bandwidth required to transmit the data. Higher bandwidth efficiency means more data can be transmitted in the available bandwidth.

Correct Statement

The correct statement for the coherent binary PSK is that the bandwidth efficiency is 0.5, and carrier synchronization is required.

Explanation

The bandwidth efficiency of coherent binary PSK is 0.5, meaning that only two bits can be transmitted per symbol. This is because the phase of the carrier wave is used to transmit digital symbols, and only two phases are available.

Carrier synchronization is required for coherent binary PSK because the receiver needs to know the carrier wave's phase to correctly demodulate the received signal. Without carrier synchronization, the receiver will not be able to distinguish between the two phases and decode the received signal correctly.

Therefore, option 'A' is the correct answer - the bandwidth efficiency is 0.5, and carrier synchronization is required.
