Abstract
This chapter considers the bit error rate performance of digital signaling on frequency nonselective (flat) fading channels with additive white Gaussian noise (AWGN). We first introduce a vector representation for digital signaling on flat fading channels with AWGN. Later, a generalized analysis is provided for the error rate performance of digital signaling on flat fading channels. We then derive the structure of the optimum coherent receiver for the detection of known signals in AWGN. The error probability performance of various coherently detected digital signaling schemes is considered, including phase shift keying, quadrature amplitude shift keying, orthogonal signals, and orthogonal frequency division multiplexing. Other types of detection schemes include differential detection of differentially encoded binary phase shift keying and differentially encoded π ∕ 4-phase shifted quadrature phase shift keying. We also consider noncoherent detection of orthogonal signals. Finally, we consider coherent and noncoherent detection of continuous phase modulated signals.
