ABSTRACT:
A method and system for wireless communications between base and mobile stations use reference signals transmitted from base stations prior transmission of data signals. The reference signals are used to determine propagation characteristics of communication channels between the base and mobile stations and optimize, in real time, parameters of receivers of the mobile stations for processing the following data signals. Applications of the invention include wireless communication systems compliant with OFDMA, 3GPP LTE, RFN-OFDMA, OFDM, TDMA, and the like communication protocols.
