Abstract : We present an approach toward improving the output signal to noise power ratio of a discrete time matched filter by employing a continuous time filter. The approach exploits the bandlimited nature of the unknown continuous time signal, and results in a filter which is robust to this inexact knowledge. We futhermore show that the robustness property does not severely compromise performance; in fact, the resulting filter possesses an output signal to noise power ratio which upper bounds that of the corresponding discrete time filter.
