| Summary: | The invention provides a frequency error detection device, a frequency error detection method, and a receiving device, being capable of detecting frequency error by relatively low computation. A first frequency error detecting portion (21) is provided with a known signal extraction portion (31), a complex operation portion (32), a reference signal supplying portion (33), a correlation operation portion (36), and a peak detection portion (37). The known signal extraction portion (31) extracts and receives known signals from symbol signals. The complex operation portion (32) executes first complex operation on a sequence receiving the know signals to eliminate phase rotation components. The reference signal supplying portion (33) provides a reference complex signal sequence which is generated by executing a same operation with first complex number operation on a sequence of the known signals. The correlation operation portion (36) calculates distribution of cross-correlation values between an output sequence of |
