Abstract
In a wireless communications system, such as a multiband Ultra Wideband communications system, data is transmitted by means of the phases of pulses in multiple frequency bands. A signal is transmitted with a predetermined phase in at least one of the frequency bands for at least a part of the time, and can be used to allow accurate detection of the phases of the signals transmitted in the other frequency bands. One of the frequency bands can be designated as a reference band, and pulses can be transmitted with constant phase in the reference band. More generally, pulses can be transmitted in the other frequency bands with phases which have a known relationship with the phases of the pulses in the reference band.
