Oqpsk bandwidth efficiency
WebLet η denote the bandwidth efficiency, and assume that the Nyquist pulse shape is used. (Ignore the fact that Nyquist pulse shaping would remove constant envelope properties.) (a) η = 4 bits/s/Hz, coherent detection (b) η = 3 bits/s/Hz, coherent detection, constant-envelope signaling (c) η = 1 bits/s/Hz, noncoherent detection WebError and Bandwidth Efficiency for a QPSK transmission system. Root Raised Cosine (RRC) and Raised Cosine (RC) Pulse-shaping filters have been used for comparison. The measurement results serve as a guideline to the system designer to select the proper …
