Abstract

The convergence and tracking properties are considered for an adaptive multielement integrated receiver structure operating in the presence of impulsive or burst noise. The receiver structure is integrated in the sense that it incorporates both the spatial/temporal predetection processing and demodulation functions in a single entity. This integrated receiver structure which was previously described by the authors (ibid. , vol. IT-32, pp. 195-219, Mar. 1986), approximates maximum-likelihood (ML) reception in the presence of both intersymbol interference (ISI) and spatially distributed interference (SDI) when the latter is modeled as zero-mean Gaussian noise. The present work is devoted to a simulation study of the convergence properties of this receiver structure when the SDI is replaced by non-Gaussian impulsive or burst noise. Results indicate that the convergence characteristics are relatively insensitive to the statistics of the SDI provided that second-order properties are held fixed, at least for moderate deviations from Gaussian behavior. For high impulsive SDI environments, however, the adaptive system exhibits a complete failure to converge.
