Channel Estimation Algorithms for MB-OFDM Based UWB System

To achieve an accurate channel impulse response (CIR) during channel equalization and coherent detection, the channel estimation plays an important role to the performance of system, especially the receiver. In this paper, we investigated two main kinds of channel estimation methods for MB-OFDM based UWB system. The performances are compared using MATLAB simulation. The simulation shows the NBIDCE algorithm has better performance for WBAN-based healthcare systems.
