Sub-Terahertz Low Power UWB Communication Link for WPAN

proposed is  ultra-wideband (UWB) wireless communication system for transmitting digital information in the terahertz frequency range on the basis of analog  noise carrier with a low level of radiation. The digital information at the transmitter is inserted using code spectrum modulation of noise signal. The bit error rate (BER) performance is analyzed for different signal to noise ratios at the receiver at different bit rates. The proposed UWB wireless communication system is characterized by high noise immunity and the ability to secure transmission of information "in the noise" for the received information signal below the noise level. The designed UWB sub-terahertz communication link at 70 microwatt transmit power is suitable for wireless personal area networks. Keywords: ultra-wide band UWB, WPAN, code spectrum modulation

An automatic measuring complex for electromagnetic field investigation

The paper describes the structure of an automatic measuring complex for inquiries into electromagnetic fields. The new complex permits to lower measurement errors due to decomposition of the wave under investigation in two orthogonal polarized bases. A new antenna system is developed making it possible to choose a convenient (for the human operators of radio control) rectangular system of spatial coordinates
