Abstract

The concept of signal-to-noise ratio (SNR) enhancement in impulse radio transceivers based on phasers of opposite chirping slopes is introduced. It is shown that SNR enhancements by factors M² and M are achieved for burst noise and Gaussian noise, respectively, where M is the stretching factor of the phasers. An experimental demonstration is presented, using stripline cascaded C-section phasers, where SNR enhancements in agreement with theory are obtained. The proposed radio analog signal processing transceiver system is simple, low-cost and frequency scalable, and may therefore be suitable for broadband impulse radio ranging and communication applications.
