Abstract
There is described a method of transmitting an ultra wideband (UWB) signal. The method comprises, inputting an information signal, generating a pseudo random time hopping code; generating a pulse inversion code and using the pseudo random time hopping code, pulse inversion code and information signal to generate the UWB signal. The time hopping code is used to modulate pulses of the signal in a pseudo random manner in order to channelise the signal whilst the pulse inversion code is used to provide additional modulation to pulses of the signal in order to further randomise the signal.
