Abstract
A radio transmitter () comprises an encoder () that receives one or more variable message bits, and encodes each message bit that has a first value as a predetermined first binary chip sequence and encodes each message bit that has the opposite value as a predetermined second binary chip sequence. The radio transmitter () transmits data packets, each comprising (i) a predetermined synchronization portion, comprising one or more instances of the first binary chip sequence, and (ii) a variable data portion, comprising one or more encoded message bits output by the encoder. A radio receiver () receives such data packets. It uses the synchronization portion of a received data packet to perform a frequency and/or timing synchronization operation, and then decodes message bits from the data portion of the data packet.
