PROBLEM TO BE SOLVED: To provide a receiver which receives a signal propagated via a different path by transmission antenna diversity, separates a pilot signal, estimates propagation path characteristics and simplifies data demodulation. SOLUTION: A receiver is provided with a receiving antenna 100, a pilot inverse diffusion part 101, a data invert diffusion part 102, a pilot separator 103, a data demodulator 105 and a deciding part 106. The separation of pilot signals, filtering processing and formation of a propagation path estimate are conducted in the single pilot separator 103, whose output is processed as a signal from the part 102, which is the data recorded in a data demodulator 105, and becomes a demodulation output going through the deciding part 106. |
