Patent ID: 8718099

Claim:
A reception apparatus for receiving a transmission signal, as a reception signal, obtained by converting a transmission data series into a frequency-domain and converting the frequency-domain converted signal into a time-domain signal, the apparatus comprising: a memory configured to store a first preamble pattern; a preamble pattern generation unit configured to read the first preamble pattern from the memory, and output at least two preamble patterns among the first, second and third preamble patterns, the second and third preamble patterns including bit series in which each of bits of the first preamble pattern is continued for n bits (where n is an integer equal to or greater than 2) and for k bits (where k is an integer equal to or greater than 2, and k≠n); a detection unit configured to detect synchronization timing based on the reception signal and the at least two preamble patterns output from the preamble pattern generation unit; and a reception processing unit configured to perform reception processing of the reception signal in synchronization with the detected synchronization timing.
