In this letter, we propose a novel approach to UWB waveform design based on sequence optimization for the multipath transmission channel. The transmit waveform is made up of a train of delayed and scaled pulses, the amplitudes of which can be represented by a real-valued sequence. The waveform results in substantial improvement in energy capture (and thus performance) over the traditional rake receiver and the more recently proposed transmitted reference approaches with a simple receiver structure. The design exploits the rich multipath structure of UWB channels allowing improved energy capture
