Abstract
A noncoherent detection scheme for differentially encoded amplitude- a nd phase-shift-keyed data transmission, assisted with differentially p hase-shift-keyed preamble signals, is presented and analyzed for an ad ditive white Gaussian noise channel. It is analytically shown that, de spite a controllable reduction in bandwidth efficiency, the proposed s cheme yields an error performance approaching that of the quadrature a mplitude modulation scheme with ideal coherent detection within a loss of approximately 1 dB.
