| Summary: | In this study, a novel Ultra Wideband (UWB) pulse generator design for single- and multi-user
systems is presented. The proposed pulse generator is based on new simple and effective design to generate
the UWB pulses through sine wave shaping. For single-user systems, three models for the proposed pulse
generator working with Frequency Modulation (FM), Bi-Phase Modulation (BPM) and On-Off Keying
(OOK) are introduced. The first generator model has 250 Mbps throughput from a 250 MHz sine wave
oscillator, while the second model works on 500 Mbps. The third model for three separate users for multiuser systems using Frequency Division Multiple Access (FDMA), while the same model can be configured
to work for a single-user with 750 Mbps using Multiple Input Multiple Output (MIMO) technique. The
generated pulse is compatible with the Federal Communication Commission (FCC) regulations of UWB
indoor emission mask. A lumped low pass filter has been designed to achieve the sine wave shaping. The
simulation results verify the proposed design and its effectiveness of using sine wave shaping for UWB
pulse generators. |
