Abstract :
The IEEE 802.15.3a model for UWB channel models is introduced in this paper. The least-squares (LS) channel estimation on the basis of pilot and linearity insertion are described. Wavelet de-noising for semi-blind channel estimation of multiband Orthogonal Frequency Division Multiplexing (OFDM) based on WPANs UWB system was added. Compared with conventional method, the proposed framework can reduce the influence of noise.
