Patent ID: 8279953

Claim:
A transmitting apparatus comprising: a first generating section that generates a plurality of information symbols from information data; a second generating section that generates a pilot symbol from pilot data of a known and invariant pattern; an adding section that adds a guard interval only immediately before the pilot symbol; a transmitting section that transmits a signal having a frame configuration where the plurality of information symbols follow the pilot symbol to which the guard interval is added; a plurality of transmitting antennas; and a determining section that determines an arrangement pattern of a plurality of the pilot symbols where the plurality of the pilot symbols corresponding to the plurality of the transmitting antennas are orthogonal to each other, wherein the transmitting section transmits streams, each stream having a pilot symbol to which a guard interval is added arranged therein and the plurality of information symbols arranged following the pilot symbol, from the plurality of transmitting antennas according to the determined arrangement pattern, and wherein the determining section determines the arrangement pattern where, during a period in which a pilot symbol corresponding to one transmitting antenna is arranged, pilot symbols and information symbols corresponding to other transmitting antennas are not arranged.
