Patent ID: 8873679

Claim:
A reception apparatus, comprising: a receiver to receive an Orthogonal Frequency Division Multiplexed (OFDM) signal by modulating a common packet sequence that is configured from a packet common to a plurality of streams and a data packet sequence that is configured from a plurality of packets individually unique to the plurality of streams; a counter, in a processing circuitry, to count an elapsed time that is relative to a predetermined time that is a reference time indicated by additional information added to particular packets of the common packet sequence and the data packet sequence, the particular packets obtained by demodulating the received OFDM signal; a detector, in the processing circuitry, to detect a displacement in a time direction between the particular packets of the common packet sequence and the data packet sequence by comparing the counted elapsed time and an additional time with each other, the additional time indicated by the additional information added to a first packet of the particular packets of the common packet sequence and the data packet sequence that is later in time that a second packet of the particular packets of the common packet sequence and the data packet sequence; and a corrector, in the processing circuitry, to correct the displacement in the time direction between the particular packets of the common packet sequence and the data packet sequence direction based on the detected displacement by correcting a readout timing of the particular packets of the common packet sequence and the data packet sequence.
