In this paper, novel active matched filter synthesis and design for UWB impulse radio lower band (3–5 GHz) is presented. Based on tapped delay line structure, the matched filter delays and sums UWB signal coherently to improve output signal to noise ratio (SNR). A four stages matched filter with a full cycle delay at centre frequency (4 GHz) is proposed. It has a measured power gain of 13.9 dB and...
In this paper, a Modified Phase-Only Correlator (MPOC) is proposed for resolving overlapped Ultra Wideband (UWB) radio pulses in order to achieve high-resolution multi-target UWB ranging. A Phase-Only Correlator (POC) is able to deconvolve the multi-target UWB channel from the received signal spectrum and its impulse-like output enables it to resolve UWB signals that are overlapping. However, the...
