Patent ID: 7987413

Claim:
A transmitter comprising a channel encoder configured to encode information bits onto a control channel, the transmitter comprising: a cyclical redundancy check (CRC) encoding block configured to receive the information bits, generate CRC bits, and add the CRC bits to the information bits forming input symbols; a tail-biting convolutional encoder coupled with the CRC encoding block, the tail-biting convolutional encoder configured to generate output symbols from the input symbols using a tail biting technique, wherein said tail-biting convolutional encoder convert (k) input bits into a sequence of (n) bits using the formula R=k/n, wherein (R) is the effective rate of the encoder and k=b+c, wherein (b) is a plurality of bits generated by the CRC from the information bits and (c) is the number of CRC bits generated by the CRC encoding block; and a modulation block configured to modulate the output symbols.
