Channel Estimation and Signal Detection for UWB

Abstract:

In this paper, we investigate channel estimation and signal detection for UWB communications. We first investigate channel estimation for UWB systems and then develop a minimum mean-square-error (MMSE) Rake receiver with joint timing and MMSE equalization. The key property of the estimator is that it uses sampling at UWB symbol rate (200Msamples/s), while estimating all relevant channel parameters for the full 7.5 GHz channel bandwidth. Computer simulations verify the usefulness of our approach for channel estimation and signal detection.
