A new class of Planar Ultrawideband Modular Antenna (PUMA) arrays, termed PUMAv3, is introduced to offer improved performance and further meet demand needs for multifunctional systems. PUMAv3 extends ...
We experimentally demonstrate a power-efficient BPSK coded ultrawideband(UWB) signal generator. The 2.5 Gb/s BPSK coded signal is achieved through optical switching based on two intensity modulators d...
A new method to reduce the computational complexity of the turbo decoding in ultrawideband (UWB) orthogonal frequency division multiplexing (OFDM) system is proposed. Existing stopping techniques for ...
We report two approaches to generate optical ultrawideband (UWB) signals using quadratic nonlinear interactions in periodically poled lithium niobate (PPLN) seeded by either normal or dark pulses. Pai...
Dear colleagues, the fourth International Conference 揢ltrawideband and Ultrashort Impulse Signals?/font> will be held in Sevastopol, the Crimea, Ukraine, September 15-19, 2008. The reports about pre...
