Performance Evaluation of MB-OFDM UWB Systems Based on Optimization Algorithm for CP Decomposition

摘要

In this paper, a Canonical Polyadic (CP) tensor decomposition for Ultra WideBand (UWB) based MultiBand Orthogonal Frequency Division Multiplexing (MB-OFDM) systems is presented. Therefore, the conventional MB-OFDM, which is a multibanding technique of Ultra WideBand technology that differs in approach from the impulse Direct-Sequence (DS-UWB) is introduced. An application of the proposed Canonical Polyadic decomposition, with isolation of scaling matrix to MB-OFDM system is proposed. A simple blind receiver based on the enhanced gradient algorithm is then presented. For illustrating this application, computer simulations are provided to demonstrate the good behavior of these algorithm compared to others in the literature.
