Based on analyzing the properties of Legendre wavelets, the extended Legendre wavelets, defined on interval (-r, r), is achieved and its properties are considered. According to the translation property of Legendre wavelets, another method for computing operational matrix of integration P is presented through integrating on subintervals. Furthermore a numerical example for solving linear differential...
Sensor Network Indoor Localization Systems (SNILS) gain a significant attention these years, due to their ease of deployment and inexpensiveness. Ranging methods play basic role in the localization system, in which the RSSI (received signal strength indicator)-based ranging technique attracts the most attention. But the accuracy of the RSSI-based localization method remains a big challenge, because...
Multiple-input multiple-output (MIMO) radar has shown its great potential on. combating with target fades by averaging the target RCSs on many decorrelated channels, and hence significantly improves the system performance. The amount of decorrelated channels is mathematically represented by the rank of channel matrix. In this paper, an analysis on the rank of channel matrix for monostatic MIMO radar...
Current researches on multiple-input multiple-output (MIMO) channel treat it as a kind of Gaussian channel. Without considering the spatial-temporal correlation, considerable deviation exists in output. This paper presents a novel spatial-temporal correlation model (STCM) for MIMO channel modeling. We adopt a correlation matrix to model the spatial correlation at the base and use wave superposition...
