Abstract
A method of decoding an encoded signal includes steps of receiving the encoded signal, creating a decoding signal by delaying the encoded signal by a predetermined amount of time Δ, sampling the encoded signal using the decoding signal, and determining a value of each of a plurality of decoded bits represented by the encoded signal based on the sampling. Also, a method of operating a shift register wherein the shift register has an initialization state wherein a first binary symbol is stored in a first position and a second binary symbol different than the first binary symbol is stored in each of one or more intermediate positions and a last position. The method includes determining that the shift register is full responsive to detecting that the first binary symbol has been stored in either one of the intermediate positions or the last position.
