An Elegant Solution: An Alternative Ultra-Wideband Transceiver Based on Stepped-Frequency Continuous-Wave Operation and Compressive Sensing

For more than 50 years, since early work beginning in 1960 [1], ultra-wideband (UWB) technology has been developed to analytically verify the transient behavior of a class of transverse electromagnetic mode microwave networks. The U.S. Federal Communications Commission has defined UWB as operating with a minimum fractional bandwidth of 20% or with a minimum -10-dB bandwidth of 500 MHz [2].
