Description: Squaring circuits are an important building block for impulse-radio UWB non-coherent receivers. This work proposes a squarer, based on the quadratic law of saturated transistors. Such a circuit has already been proposed for lower frequency applications, therefore this work focuses on the extension to ultra wide bandwidth, with particular care to the consequences related to the deviation from the ideal quadratic law of 0.18μm CMOS transistors.

Description: Increasing interest in ultra-wideband (UWB) communications has engendered the need
for a test bed for UWB systems. An FPGA-based software-defined radio provides both postfabrication
definition of the radio and ample parallel processing power. This thesis presents
the FPGA design for a software-defined radio targeted to impulse ultra-wideband signals.
The system is capable of an effective sampling frequency of up to 8 G-samples/s using timeinterleaved
sampling with eight 1-GHz ADCs. The system is also capable of transmitting
UWB pulses using a transmitter board controlled by the FPGA. In this thesis, the FPGA
design used to capture and export data from the eight ADCs is presented, along with two
systems which make use of the transceiver: a pilot-based matched filter communications
system, and a remote vital signs monitor.

Description: The book focuses very much on impulse radio UWB techniques rather than multiband systems. The reasons for this are both practical and historical. The promise of UWB was low complexity, low power and low cost. Impulse radio, being a baseband technology, holds the most promise to achieve these three benefits.
