Channel estimation for a mobile terminal in a multi-standard environment (LTE and DVB-H)

Abstract

In this paper, we present an analysis of different channel estimator structures that can be used and efficiently implemented with minor configuration changes of a common hardware for both LTE and DVB-H. Such common estimator structures for LTE and DVB-H allow algorithm and hardware reuse when both standards are implemented on the same platform. In this approach, a core estimator will be utilized to address parameter estimation for the two standards. The estimators exploit similarities in pilot patterns between LTE and DVB-H. The estimation techniques are discussed taking both algorithm and complexity issues into account.
