Frequency Domain Incremental Strategies over Distributed Network

Abstract

This paper presents a frequency domain adaptive strategy based on incremental techniques. The proposed scheme represents the problem of linear estimation using frequency domain transformation methods like DCT, DFT in a cooperative manner, where nodes are having the computing ability to find the local estimation in frequency domain and sharing them among the predefined neighbours. This algorithm is distributed and cooperative in nature. In addition to this it also responds to real time environments and produces a better result than that of the incremental time domain adaptive method under colored input. Each node share information with its immediate neighbours to fully exploit the spatial dimension there by lowering the communication burden. Computer sim-ulation result illustrates the performance of the new algorithm.
