  • Abstract
    For a raised cosine pulse spectrum with pulse shaping fully at the transmitter, several enhanced receivers for pulse amplitude modulation are presented which recover some of the 1.76 dB SNR lost due to nonmatched filtering reception. Three receivers using concepts such as double-the-symbol-rate sampling, the partial response-type property of the pulse, and soft decisions are analyzed; they recover 0.6, 0.97, and 1.21 dB SNR, respectively. An error monitoring scheme is also proposed.
