1. A reception device that receives broadcasting data, the reception device comprising:
a receiver configured to receive a first broadcasting signal and a second broadcasting signal from a first transmit station and a second transmit station, respectively, the first broadcasting signal and the second broadcasting signal being transmitted at an identical time and at an identical frequency band, polarized wave of the first broadcasting signal differing from polarized wave of the second broadcasting signal, the first broadcasting signal and the second broadcasting signal being generated based on first orthogonal frequency division multiplexing (OFDM) symbols and second OFDM symbols, respectively; and
circuitry configured to decode the first broadcasting signal and the second broadcast signal to generate the broadcasting data, wherein
in the first broadcasting signal and the second broadcasting signal, pilots are inserted in the first OFDM symbols and the second OFDM symbols, 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.
