Novel cytidine deaminase-like polypeptides, proteins, and nucleic acid molecules are disclosed. A decapsulator is coupled to the receiver and configured to create datagrams and erasure attributes associated with the datagrams. The LMS algorithm is modified in accordance with whether a digital or an analog correction of the inter-stage error of a residue amplifier on the ADC is to be made. The second decoding algorithm may have an error correction capability exceeding an error correction capability of the first decoding algorithm.
