Multicarrier receiving apparatus, multicarrier communication system and demodulation method

Abstract

To suppress effects produced on other terminals as much as possible, while obtaining the advantage of soft-combining. A multicarrier receiving apparatus that receives a packet comprised of at least a propagation path estimation symbol and a scrambled information symbol to demodulate, and has propagation path estimating sections-and-that respectively estimate propagation paths of radio signals transmitted from a plurality of transmission antennas, scramble multiplying sections-and-that respectively perform the same scrambling on propagation path estimation values output from the propagation path estimating sections-and-as scrambling provided in the information symbol on the transmission antennas sides, an adding section-that adds scrambled propagation path estimation values, and a propagation path compensating sectionthat performs propagation path compensation of the information symbol included in the received packet using a signal output from the adding section-
