Space-shape coded UWB-impulse radio system

Abstract

Proposed is a novel space-shape coding scheme with multiple antennas and multiple orthonormal waveforms for UWB-IR systems. Since the proposed coding scheme can be applied for every frame, the spatial diversity can be achieved even without the invariant channel condition over frames. Furthermore, the proposed scheme can provide an additional power gain to enhance BER performance while the FCC spectral regulation is satisfied.
