If you are using simple ASK, FSK, or 2-PSK, and if the data rate is N. Then, following modulation techniques increase data rates further. 4-PSK, 4-QAM ==>2N. Because here 2 bits are sent as a symbol once. 8-PSK, 8-QAM ==>3N. Amplitude and phase-shift keying (APSK) is a digital modulation scheme that conveys data by modulating both the amplitude and the phase of a carrier wave. In other words, it combines both amplitude-shift keying (ASK) and phase-shift keying (PSK). This allows for a lower bit error rate for a given modulation order and signal-to-noise ratio, at the cost of increased complexity, compared to ASK o… think physics pradeep gamage
