Time Decoding Machine - Threshold-Insensitive Real-Time Decoder [10]

Decodes a bandlimited, arbitrarily long signal encoded by an Asynchronous Sigma-Delta Modulator by stitching together blocks of data decoded by solving a Vandermonde system using the Björk-Pereyra Algorithm. This reconstruction method does not require the specification of an integrator threshold.
