Consider the four-phase and eight-phase signal constellations shown below:
Assume that the symbols are equiprobable in both the constellations and the phase separation between the two adjacent points is uniform. If the distance between two adjacent points in both the constellation is same, then the excess average symbol energy (in dB) to be transmitted in eight-phase scheme compared to that of 4-phase scheme, will be
Enter numerical value using the virtual keypad. Round off where necessary.
