1. A transmission device comprising:
circuitry that:
encodes broadcasting data according to a multi-antenna encoding scheme to generate first orthogonal frequency division multiplexing (OFDM) symbols and second OFDM symbols;
inserts pilots in the first OFDM symbols and the second OFDM symbols; and
generates a first broadcasting signal and a second broadcasting signal based on the first OFDM symbols and the second OFDM symbols, respectively, after the pilots are inserted; and
a transmitter that transmits the first broadcasting signal and the second broadcasting signal from a first transmit station and a second transmit station, respectively, wherein
the first broadcasting signal and the second broadcasting signal are transmitted at an identical time and at an identical frequency band,
polarized wave of the first broadcasting signal differs from polarized wave of the second broadcasting signal, and
density of the pilots in a frequency direction in one of the first OFDM symbols is lower than density of the pilots in the frequency direction in one of the second OFDM symbols.
