Latest Patents

Sangster holds a patent for a "Synchronizing technique for an error correcting digital transmission." This invention encompasses a system that includes an encoder and a decoder for the effective transmission and retrieval of digital data over a transmission medium. The encoder employs an error correction encoding scheme that processes data to produce an encoded bit stream, which includes both data and parity bits. The transmission bit stream is generated by modulo-2 adding the encoded bit stream with a predetermined sync sequence, optimizing sync detection at the decoder site. The decoder then utilizes this sync sequence to monitor errors in the resultant bit stream, providing indications of synchronization status.
