Abstract:
1. An apparatus for wirelessly communicating a leading bit string comprising a header and a body, and a trailing bit string comprising a header and a body, the apparatus comprising: an encoder configured for encoding a data bit stream and a parameter bit stream to form the body of the leading bit string, and forming the header of the trailing bit string to include at least one bit of a parameter to be used by a receiver in decoding the data bit stream and the parameter bit stream, the encoding is achieved by applying a fixed code; and a transmitter configured for transmitting to the receiver a wireless signal representing at the receiver the leading bit string and then the trailing bit string, the encoded bit-stream is modulated to produce a signal whose frequency range at any given time is predetermined independently of the fixed code; wherein the encoder includes a data encoder for encoding the data bit stream and a parameter encoder for encoding the parameter bit stream, a portion of the parameter bit stream being used during encoding in cooperation with a parity bit.
