Title:
WIRELESS COMMUNICATION APPARATUS, WIRELESS COMMUNICATION METHOD, AND NON-TRANSITORY COMPUTER READABLE MEDIUM IN WHICH COMMUNICATION CONTROL PROGRAM IS STORED
Document Type and Number:
WIPO Patent Application WO/2010/134265
Kind Code:
A1
Abstract:
Disclosed are a wireless communication apparatus, wireless communication method, and communication control program, wherein changes in the state of a communication channel can be estimated directly. The wireless communication apparatus is a wireless communication apparatus which performs co-channel transmission using orthogonally polarized signals. The wireless communication apparatus is provided with a polar signal reception unit (1) which receives one of the polarized signals transmitted to the wireless communication apparatus as a polar signal, and a cross polar signal reception unit (2) which receives a cross polar signal which is orthogonal to the polar signal that the polar signal reception unit (1) receives. Further, the wireless communication apparatus is provided with a communication channel status estimation unit (3) which estimates the state of the communication channel, based on information pertaining to the cross-polarization interference generated between the polar signal received by the polar signal reception unit (1) and the cross polar signal received by the cross polar signal reception unit (2).
