Direct Sequence Spread Spectrum UWB Channel Data Estimation Method Based on OBE

The discrete DS-UWB channel estimation problem is modeled by the knowledge of set theory, and an UWB channel estimation algorithm based on OBE algorithm is proposed. The influence of different spreading codes on the estimated mean square error of the channel is analyzed. Simulations show that even in the case of unknown channel lengths, the channel tap values are well estimated in a determinate dimensional space.
