Differential amplitude phase-shift keying (DAPSK), which is also known as star-shaped quadrature-amplitude modulation, has implementational advantages not only due to dispensing with channel estimation but as a benefit of its low signal detection complexity as well. It is widely recognized that separately detecting the amplitude and the phase of a received DAPSK symbol exhibits lower complexity than jointly detecting the two terms. However, since the amplitude and the phase of a DAPSK symbol… CONTINUE READING
