<p>Provided is a diversity reception device that has the BER improved, and that does not require carrier synchronization, just by having a simple construction that is provided with: a power combiner (14) that combines electric powers of OFDM signals received by a first antenna (A1) and a second antenna (A2); a switch (S) that switches between a branching output of the first antenna (A1) and a branching output of the second antenna (A2), for each of the symbol sections, at a timing halfway through the effective symbol section of the OFDM signal; a receiver (21) that demodulates the OFDM signals; a phase shifter (13) that shifts the phase of the OFDM signal received by the second antenna (A2); and a calculation processing circuit that calculates a complex correlation-coefficient between a guard section of the first antenna (A1) and a copy-source section of the second antenna (A2), for each of the symbol sections, from a phase control signal, and obtains a rotation angle from the complex correlation-coefficient.</p> |
