A transmission apparatus includes: a multiplier configured to multiply a signal provided on a complex plane by a multiplication coefficient corresponding to a number of transmission sub-carriers; and an inverse fast Fourier transformer configured to perform an inverse fast Fourier transform on the multiplied signal.

Circuit transmission apparatus and transmission method

A transmission apparatus for converting a transmission data series into frequency-domain, converting the frequency-domain converted signal into time-domain signal, and transmitting the time-domain converted signal, the apparatus including: a preamble pattern generation unit which outputs at least two preamble patterns among second and third preamble patterns, including bit series in which each of bits of a 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&#x2260;n), and the first preamble pattern; and a transmission unit which transmits the transmission signal including at least two of the preamble patterns output from the preamble pattern generation unit.
