Abstract :
Hardware considerations and system parameter tradeoffs are examined for the implementation of a real-time spectral encoded ultra-wideband transmitter. The effects of symbol length, chirp bandwidth, and spreading sequence are described, and two possible implementations are examined for their spectral shaping performance, cost, and power dissipation. One implementation is based on surface acoustic wave chirp filters to perform the Fourier transforms in realtime. The other is based on a high speed memory and digital-analog converter, where all components are integrated on-chip
