16 psk block diagram?Advertisement
Phase-shift keying (PSK) is a digital modulation scheme that conveys data by changing, or modulating, the phase of a reference signal (the carrier wave). - read more
Because there are two PSK signals combined, in quadrature, the two-channel modulator gives rise to a quadrature phase shift keyed - QPSK ... illustrated in idealised from in the block diagram of Figure 3. It is idealised because it assumes the incoming signal has its two DSBSC precisely in phase ... - read more
