Patent ID: 8908794

Claim:
A wireless sending apparatus, comprising: a change judging means to judge whether changing an interference causing avoiding transmission means, which is applied to each predetermined frequency-domain group of a sending signal, on the basis of predetermined change judging information, and to output a judgment as a change judgment result; a signal separating means to separate the sending signal into each the group on the basis of the change judgment result; a first interference causing avoiding transmission means to input the sending signal which is separated into each the group, and to reduce leak power, which leaks outside a sending frequency band, by a time-domain process; a second interference causing avoiding transmission means to input the sending signal which is separated into each the group, and to reduce the leak power, which leaks outside the sending frequency band, by a frequency-domain process; and a synthesizing means to synthesize the sending signals which the first interference causing avoiding transmission means and the second interference causing avoiding transmission means carry out an interference causing avoiding process to respectively and supply respectively, wherein the sending signal is sent per the group by use of any one of the first interference causing avoiding transmission means and the second interference causing avoiding transmission means.
