Title:
NON-DATA-AIDED CHANNEL ESTIMATORS FOR MULTIPATH AND MULTIPLE ANTENNA WIRELESS SYSTEMS
Document Type and Number:
WIPO Patent Application WO2007101338
Kind Code:
A8
Abstract:
Novel non-data-aided maximum likelihood estimators for the delays and the attenuations in an ultra-wide bandwidth channel are proposed. Numerical results show that these new estimators outperform the previous non-data-aided maximum likelihood channel estimators derived in the literature. Moreover, in some cases, the performances of the new non-data-aided estimators approach those of the data-aided estimators, enabling us to reduce the overhead expense of pilot symbols.
