ANTENNA DIVERSITY COMMUNICATION DEVICE

摘要

PURPOSE: An antenna diversity communication device is provided to improve communication performance by adapting frequency hopping to antenna diversity communication well. CONSTITUTION: A switching unit(12) alternatively selects one antenna among a plurality of antennas(10,11). A signal information measuring unit(13) measures the receiving condition of the selected antenna. A channel frequency memory unit(16) stores frequency difference information between a current channel and the next channel. A switching control unit(15) controls the switching unit(12) in which the antenna is switched on the basis of frequency correlation between the current channel and the next channel. The switching control unit(15) also stores signal information measured by the signal information measuring unit(13) and selects the antenna on the basis of stored signal information.
