    A Generalized Matched Filter1992Conference paper (Refereed)
    Abstract [en]

    Parameter estimation in additive independent identically distributed noise is treated. It is shown that there exists a generalized form of the matched filter which can be used for an arbitrary noise distribution to make e.g. ML-, MAP- or MMSE-estimates of a parameter vector. Simulations are presented to illustrate the performance.

    A Simultaneous Maximum Likelihood Estimator Based on a Generalized Matched Filter1994Conference paper (Refereed)
    Abstract [en]

    This paper discusses parameter estimation and detection in laplace distributed noise. The received signal is modeled as r($DOT@) $EQ As($DOT@,$theta@) $PLU n($DOT@), where A is an unknown amplitude, $theta is the parameter vector to be estimated and n($DOT@) is independent laplace distributed noise. The simultaneous maximum likelihood estimator of (A,$theta@) is derived. The derived estimator is based on a combination of a weighted median filter$LB@1$RB and a generalized form of the ordinary matched filter$LB@2$RB@. Examples of performance for four different detectors are given for a case of binary detection, when the amplitude A or the signal shape s($DOT@,$theta@) are varied. Simulations indicate that the performance of detectors based on the generalized matched filter is not particularly dependent on either the estimate of the amplitude A or the signal shape.

    Simultaneous Channel and Symbol Maximum Likelihood Estimation in Laplacian Noise1998Conference paper (Refereed)
    Abstract [en]

    This paper treats channel estimation and signal detection in Laplacian noise. The received signal is assumed to be a transmitted signal which has been corrupted by an unknown channel, modeled as a FIR filter, the output being further disturbed by additive independent Laplacian noise. The transmitted signal is assumed to depend on an unknown parameter belonging to a known finite set. The simultaneous maximum likelihood (ML) estimator of the unknown parameter, as well as of the FIR filter coefficients, is derived. The ML estimate of the channel can be obtained by using a linear programming approach and the decision about the parameter is based on the output from a set of generalized matched filters. Simulation results are included in order to illustrate the performance of the proposed receivers.
