Abstract
A communication apparatus includes unit measuring a first interference feature quantity indicating a state of an interference signal in a transmission frequency band (TFB), unit determining from the first interference feature quantity whether the interference signal exists in the TFB, unit acquiring, after measurement of the first interference feature quantity, a transmission channel from a second interference feature quantity measured by the measuring unit, the transmission channel corresponding to at least one of a frequency orthogonal to the interference signal, a time orthogonal to the interference signal, a space orthogonal to the interference signal, and a spreading code orthogonal to the interference signal, and unit performing a first transmission using the TFB when it is determined that no interference signal exists in the TFB, and to perform a second transmission using the transmission channel when it is determined that the interference signal exists in the TFB.
