Simulating the performance of different modulation schemes.
Binary Phase Shift Keying (BPSK) is a two phase modulation scheme, where the 0's and 1's in a binary message are represented by two different phase states in the carrier signal: theta = 0 for binary 1 and theta = 180 degrees for binary 0.
Random Generator set size = 2
Quadrature Phase-Shift Keying Modulation ( QPSK ) is a form of Phase Shift Keying in which two bits are modulated at once, selecting one of four possible carrier phase shifts (0, 90, 180, or 270 degrees).
Random Generator set size = 4
Phase offset = pi/4
Frequency Shift Keying ( FSK ) is a frequency modulation scheme in which digital information is transmitted through discrete frequency changes of a carrier signal.
Random Generator set size = 2
M-ary number = 2
Quadrature Amplitude Modulation ( QAM16 ) is a signal in which two carriers shifted in phase by 90 degrees (i.e. sin and cos) are modulated and combined. As a result of their 90 phase difference they are in quadrature and this gives rise to the name. Often one signal is called the In-phase or I signal, and the other is the quadrature or Q signal.

Quadrature Amplitude Modulation ( QAM64 ) is a signal in which two carriers shifted in phase by 90 degrees (i.e. sin and cos) are modulated and combined. As a result of their 90 phase difference they are in quadrature and this gives rise to the name. Often one signal is called the In-phase or I signal, and the other is the quadrature or Q signal.
