System Design Considerations for Ultra-Wideband Communication
Overview This paper discusses issues associated with high-data-rate pulsed ultra-wideband system design, including the baseband processing, transmitter, antenna, receiver, and analog-to-digital conversion. A modular platform is presented that can be used for developing system specifications and prototyping designs. This prototype modulates data with binary phase shift keyed pulses, communicates over a wireless link using UWB antennas and a wideband direct conversion front-end, and samples the received signal for demodulation. The MultiBand OFDM Alliance (MBOA) proposal for 802.15.3a uses Orthogonal Frequency-Division Multiplexing (OFDM) modulation in a bandwidth of 528 MHz. It represents a very elegant solution to the multipath problem that appears in UWB systems. On the other hand, it requires either more stringent linearity than a pulsed UWB system or the presence of a coding scheme.
