Patent ID: 8467484

Claim:
A reception control method for a wireless communication apparatus having a plurality of antennas, comprising: a recognition step of recognizing a peak output of a guard interval correlator and/or recognizing a number of samples exceeding a predetermined power value in a predetermined period from output of the guard interval correlator with respect to a received signal; and an antenna directivity control step of changing directivity of an antenna in the plurality of antennas when the recognized peak output falls below a first predetermined value and/or the number of samples exceeds a second predetermined value, wherein, the plurality of antennas include a first antenna and a second antenna that have directivities different from each other, at the antenna directivity control step, the directivity of the antenna in the plurality of antennas is changed by switching from the first antenna to the second antenna when the peak output falls below the first predetermined value and/or the number of samples exceeds the second predetermined value, at the recognition step, the peak output of the guard interval correlator is recognized and/or the number of samples exceeding the predetermined power value in the predetermined period is recognized from the output of the guard interval correlator with respect to a received signal of at least the first antenna, and at the antenna directivity control step, the directivity of the antenna in the plurality of antennas is changed and a symbol timing of a frame of the received signal of the first antenna is changed to a symbol timing of a frame of a received signal of the second antenna by switching from the first antenna to the second antenna when the peak output falls below the first predetermined value and/or the number of samples exceeds the second predetermined value.
