In this paper, we propose an efficient ranging technique using chirp signal, which employs a matrix pencil method to estimate time of arrival (TOA). The proposed TOA estimation method consists of a two-step signal processing: minimum mean square error (MMSE)-based channel impulse response estimation and the channel delay tracking by matrix pencil algorithm. At the first step, the transmitted known...
In this paper, we propose a zero padded single-carrier (SC) block transmission with minimum mean squared error-frequency domain equalization (MMSE-FDE) for impulse radio ultra-wideband (IR-UWB) systems. Moreover, the comparative study among the proposed scheme and the conventional one is presented. The proposed zero padded MMSE-FDE not only has the favorable advantages of the existing cyclic prefixed...
