Abstract: A bitstream modifier is operative on a packet which uses repetition coding. The bitstream modifier increases randomness of the data in a deterministic manner such that spectral spurs from repetition coding are greatly reduced, thereby providing greater available transmit power. In another example of the invention, baseband samples of a header and/or payload for a Bluetooth packet are modified by a canonical sequence with a low slew rate for data such that the variations in frequency may be tracked by a receiver and the transmitted spectral spurs reduced.
