Real Time Position Location & Tracking (PL&T) Using Prediction Filter and Integrated Zone Finding in OFDM Channel
Authors: ,
Abstract: The nature of pre-determined and on-demand mobile network fabrics can be exploited for Position Real time Location Tracking (PL&T) of radios and sensors (nodes) for Global Positioning System (GPS) denied or GPS-free systems. This issue is addressed by a novel system of integrating zone finding and triangulation method for determining the PL&T of nodes when MANET is employed based on using directional antennas for radio communications. Each mobile node is switched dynamically between being a reference and a PL&T target node to improve the accuracy of predicting the PL&T of each node. This paper presents the Baseline PL&T with predictive Kalman filter and Integrated zone based PL&T algorithm design that integrates zone finding and triangulation method. The performance of the proposed algorithm is analyzed in Rayleigh and Rician based on the Orthogonal Frequency Division Multiplexing (OFDM) system using efficient Interleaving-KV sample coding & error correction scheme under multipath faded channel.
