Abstract
A channel structure that can efficiently transmit more data control bits, e.g., required by future wireless communication systems, yet achieve sufficient detection and false alarm performance uses tail-biting convolutional coding and Cyclical Redundancy Check (CRC). In certain implementations, symbol repetition, interleaving and/or scrambling can also be included. Also, depending on the implementation, modulation schemes such as Bi-Phase Shift Keying (BPSK), Quadrature Phase Shift Keying (QPSK) or Quadrature Amplitude Modulation (QAM) can be used in conjunction with the other coding techniques.
