| Summary: | This paper examines the impact of asymmetric pulses in NRZ waveforms generated by
maximum-length sequences and used in spread spectrum systems. The data asymmetry
phenomenon is produced by differential propagation delays through logic circuits in the
payloads. A model of three elementary pulse shapes is employed to characterize the
signal source and the occurrence probabilities for each is calculated. The autocorrelation
function of the waveform is eventually obtained taking into account the asymmetry, and
some numerical evaluations are finally presented to show the deviation from the
theoretic case where no asymmetry is considered. |
