ABSTRACT:
An ultra wide band (UWB) communication system includes a channel filter bank to cover the 3.1 to 10.6 GHz band in channels having approximately equal bandwidth. A transmitter and a receiver may share the filter bank when the communication system is configured as a transceiver. The transmitter produces short duration, wide bandwidth RF pulses by triggering the impulse response of one or more of the filters of the filter bank. The impulse response is triggered by applying a very short duration time domain signal produced using a single pulse mixer and a step recovery diode circuit. The receiver uses a square-law detector to detect RF signals passed by the channel filter bank and the detected signals are further processed to extract a data signal and a confidence level in the data signal.
