A preamble receiving apparatus includes a receiving unit receiving from a transmitting apparatus a frame having a format which contains a preamble section and a margin section subsequent to the preamble section; and a reception processing unit (14) detecting a preamble signal which is transmitted in the preamble section in the transmitting apparatus from the received frame, wherein the reception processing unit includes: a correlation processing unit (15) which defines as a search section a time having a predetermined starting point and which is equal to or shorter than the margin section, and creates a power profile for each of divided sections through a correlating process operation related to a plurality of divided sections obtained by dividing the search section ; and a coupled profile creating unit for creating a coupled power profile by coupling the power profile for each of the divided sections to each other. |
