Coherent detection of bpsk
WebBPSK Signal Costellation • The receiver implementation can affect the performance. – Coherent detection • receiver will exploit the exact knowledge of the phase of the carrier to detect the signal better. – Non-coherent detection • involves making some approximations to the phase information that results in a loss in performance. However, WebBPSK (also sometimes called PRK, phase reversal keying, or 2PSK) is the simplest form of phase shift keying (PSK). It uses two phases which are separated by 180° and so can also be termed 2-PSK. It does not particularly matter exactly where the constellation points are positioned, and in this figure they are shown on the real axis, at 0° and 180°.
