Abstract
A new data format used in a communication system employing binary phase shift keying modulation and demodulation is described. The data format provides for a frame comprising a plurality of variable data bits and synchronization bits. The number of variable data bits in the data format of the present invention is more than the number of synchronization bits. The data format preferably includes a CRC field for error detection. In order to uniquely decode the information contained in the frame, the inverse of frame should not be a valid frame. A method for detecting invalid frames is also disclosed.
