摘要:Abstract(#br)This work presents an extension of the high-resolution RiMAX multipath estimation algorithm, enabling the analysis of frequency-dependent propagation parameters for ultra-wideband (UWB) channel modeling. Since RiMAX is a narrowband algorithm, it does not account f...

摘要:Abstract(#br)In this paper, it has been shown that non-stationary received signals at ultra-wideband impulse radars can be addressed by Fourier series model with time-varying coefficients. Next, simply by computing statistical features of the coefficients, we show that this model...

摘要:Abstract(#br)We present a new analog circuit exhibiting high bandwidth and low distortion, specially designed for signal correlation in an ultra-wideband receiver front end. The ultra-wideband short impulse signals are correlated with a local pulse template by the correlator. A c...

摘要:This paper presented a dual-band ultra-wideband bandpass filter, which employs three sets of T-shape stub-loaded resonators (TSSLRs). The new generation approaches of resonant mode (RM), which was named here as the synchronous-quasi-resonance (SQR), to generate more RMs were firs...

摘要:ABSTRACT(#br)An ultra-wideband (UWB) bandpass filter with extended upper-stopband on multilayer liquid-crystal-polymer (LCP) substrate is presented in this paper. The proposed filter is designed to select the frequency band from 1.0 to 20 GHz. The filter consists of two parallel-...
