Verfahren zur Schätzung von Kanalparametern von Funkkanälen eines W-CDMA-Mobilfunksystems

摘要

A method for estimating radio channel parameters in a W-CDMA mobile radio system, for example according to the UMTS standard. According to the inventive method, the mean value of the channel estimations of the last two sequences of known symbols following on from another chronologically is taken as a hypothesis for the channel parameters at high mobile receiver movement speeds. An interpolation is carried out between the channel parameters from the sequence of known symbols sent directly prior to the data symbols and directly afterwards at high mobile receiver speeds and low data throughput rates. An interpolation is carried out between channel parameters from the two last sequences sent prior to the data symbols at high mobile receiver speeds and high data throughput rates.
