RADIO COMMUNICATION DEVICE, RADIO COMMUNICATION SYSTEM, AND RADIO COMMUNICATION METHOD |
摘要 |
There is disclosed a radio communication device capable of preventing wire-tap of an encrypted communication even if a radio signal is wire-tapped by a third person in a radio communication system using the MIMO technique. In this device, an inter-channel correlation calculation unit (104) calculates an inter-channel correlation value between two channels in the MIMO channel according to four channel estimation values inputted from a channel estimation unit (103). The six channel correlation values calculated are all inputted to a channel selection unit (105). The channel selection unit (105) selects a minimum channel correlation value from the six channel correlation values inputted from the inter-channel correlation calculation unit (104) and reports two channels corresponding to the selected channel correlation value to an inter-channel correlation monitoring unit (110) and inputs the channel estimation value of the two channels to a secret key generation unit (106). |
