Abstract:
UWB has been a very attractive choice for medical
radar and localization applications. The use of UWB signals can
provide distance measurements with very high accuracy but a big
challenge is caused by high attenuation resulting in low signal-tonoise ratios. It is well-known that analog-to-digital conversion is
practically not feasible for UWB. Compressed Sensing is an
emerging concept which potentially could solve this problem. The
weakness of this concept is to handle noisy signals. We propose
an implementation strategy to overcome this problem. The
hardware implementation and complexity are also taken into
account. Simulation results show significant improvements
compared to conventional algorithms for both ideal and
measured signals.
