First experimental impulse-radio ultra-wideband transmission under the Russian spectral emission mask

Ultra-wideband impulse-radio wireless transmission under the stringent conditions and complex shape of the Russian spectral emission mask is experimentally demonstrated for the first time. Transmission of 1 and 1.25 Gbit/s signals over distances of 6 and 3 m is achieved with a bit error rate below 3.8 × 10−3.
