COMMUNICATION DEVICE AND COMMUNICATION METHOD

摘要

A communication device includes: a first antenna and a second antenna; a switch unit selecting the first antenna in a first term and the second antenna in a second term; a reception determination unit determining whether or not communication data contained in wireless signals received by the first antenna and the second antenna; and a storage unit storing association between each of communication terminals and one of the first antenna and the second antenna, in which the switch unit sets lengths of the first and second terms so that a ratio of the respective lengths of the first and second terms is equal to a ratio of the number of times the communication data from the communication terminals respectively associated with the first and second antennas and is determined to be successfully obtained.

1. A communication device comprising:
a first antenna and a second antenna which receive wireless signals sent by a plurality of communication terminals, the wireless signals containing communication data; a selection unit configured to select the first antenna in a first term, and the second antenna in a second term different from the first term; a reception determination unit configured to determine whether or not the communication data contained in the wireless signals received by a selected one of the first antenna and the second antenna selected by the selection unit is successfully obtained; and a storage unit which stores association between each of the communication terminals and one of the first antenna and the second antenna, wherein the selection unit is configured to set a length of the first term and a length of the second term by referring to the association, the length of the first term and the length of the second term being set to make a ratio of the length of the second term to the length of the first term equal to a ratio of the number of times the communication data sent by the communication terminal associated with the second antenna is determined to be successfully obtained, to the number of times the communication data sent by the communication terminal associated with the first antenna is determined to be successfully obtained.
