METHOD AND APPARATUS FOR PILOT MULTIPLEXING IN WIRELESS COMMUNICATION SYSTEM

Abstract

PROBLEM TO BE SOLVED: To provide pilot transmission means allowing channel estimation not influencing data performance even in the presence of inter-antenna interference and inter-transmitter interference.

SOLUTION: In a process 400 for generating an interleaved frequency division multiplexing (IFDM) pilot pilot sequences generated based on a Chu sequence with ?=1 a Chu sequence defined by a transmitter-specific ? value some other CAZAC sequence a PN sequence etc. are generated 412 for a plurality of transmit antennas in the time domain on a different set of subcarriers. A plurality of pilot transmissions are generated 414 based on the plurality of pilot sequences.
