  • Patent number: 8467462
    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 3-a and 3-b that respectively estimate propagation paths of radio signals transmitted from a plurality of transmission antennas, scramble multiplying sections 5-a and 5-b that respectively perform the same scrambling on propagation path estimation values output from the propagation path estimating sections 3-a and 3-b as scrambling provided in the information symbol on the transmission antennas sides, an adding section 3-c that adds scrambled propagation path estimation values, and a propagation path compensating section 7 that performs propagation path compensation of the information symbol included in the received packet using a signal output from the adding section 3-c.
