A message in the form of a sequence of bits is encoded into non-binary signals. The encoder (401) encodes the message into a vector as the first half of the eventual encoded vector, and append the negation of the encoded vector to the encoded vector as the second half to obtain the full-length encoded vector. An identical synchronization signal (405) is added to both halves of the encoded signal. During decoding, the decoder (501) first obtains the synchronization signal by adding the two halves of the vector to find the original cyclical shift of the vector. Afterwards the decoder decodes the , vector into a bit sequence by taking the difference of the two halves of the full-length …

Why it's free to use
- Filed April 16, 1999. No grant is recorded for it in Canada; had it been granted, its 20-year term would have ended April 16, 2019.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by April 16, 2021.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
