Abstract:
Systems and methods for using travelling pilots for channel estimation are described herein. In one aspect, wireless communications apparatus is described that comprises a processor configured to divide a plurality of tones on which pilot signals are to be transmitted among a plurality of symbols, wherein each symbol includes less than all of the plurality of tones and the plurality of symbols includes at least a subset of the plurality of tones. The wireless communication apparatus further comprises a transmitter configured to transmit, during a given symbol, pilot signals on the tones included in the given symbol, wherein the tones over which the pilot signals are transmitted are changed from symbol to symbol.
