A variety of ultrawideband system designs — from carrierless, impulse UWB (I-UWB) to multicarrier (MC) UWB — have been pursued recently. I-UWB has several advantages, including simple RF circuitry, ...
Figure 4. A snapshot, in time, of two complex numbers whose exponents, and thus their phase angles, change with time. The notion of negative frequency is often troubling to engineers who've spent so ...
