Experimental confirmation and physical understanding of ultra-high bit rate impulse radio in the THz digital communication channels of the atmosphere

چکیده
We have performed highly accurate numerical calculations of high bit rate impulse propagation through the seven digital communication channels of the atmosphere at RH 58% (10 g m). These calculations maximized bit rates for pathlengths equal to or longer than 100 m. We have experimentally verified our calculations for three channels with a propagation pathlength of 137 m and RH 65% (11.2 g m). Excellent agreement between measurement and theory was obtained for Channel 3 at 252 GHz, bit rate 84 Gb s, FWHM bandwidth (BW) 180 GHz; Channel 6 at 672 GHz, 45 Gb s, BW 84 GHz; and Channel 7 at 852 GHz, 56.8 Gb s, BW 108 GHz.

Besides common SDR concepts the developed IR transceiver employs first order bandpass (BP)...
متن کاملA New, Near-Coherent Detector Configuration for UWB Impulse Radio
Abstract—Since radio channels available have been assigned to traditional narrowband communication systems the only solution to establish new radio communication links is the frequency reuse. This has to be achieved without causing interference in the conventional radio systems. Ultra WideBand (UWB) radio uses extremely wideband wavelets to decrease the Power Spectral Density (psd) of radiated ...
متن کاملPerformance Evaluation of an Improved Multiband Impulse Radio UWB Communication System Based on Sub-Band Selection
Performance evaluation of an improved multiband impulse radio ultra-wideband (MIR UWB) system based on sub-band selection is proposed in this paper. In the improved scheme, a data mapping algorithm is introduced to a conventional MIR UWB system, and out of all the sub-bands, only partial ones are selected to transmit information data, which can improve the flexibility of sub-bands/spectrum allo...
متن کاملPerformance Analysis of CDMA, OFDM & UWB using Smart Antenna
CDMA, OFDM and UWB are the most developing technologies in modern mobile communication. OFDM is a parallel transmission scheme, where a high – rate serial data stream is split up into a set of low – rate sub streams, each of which is modulated on a separate subcarrier. Increasing the number of parallel transmission reduces the data rate that each individual carrier must convey and that lengthen...
متن کاملMultistage block-spreading for impulse radio multiple access through ISI channels
Transmitting digital information using ultra-short pulses, impulse radio (IR) has received increasing interest for multiple access (MA). When IRMA systems have to operate in dense multipath environments, the multiple user interference (MUI) and intersymbol interference (ISI) induced, adversely affect system capacity and performance. Analog IRMA utilizes pulse position modulation (PPM) and rando...
