Title:
COMMUNICATION DEVICE
Document Type and Number:
WIPO Patent Application WO/2010/150313
Kind Code:
A1
Abstract:
A communication device adds a permutation signal obtained by multiplying a fundamental signal by an integer to an information signal having information to be transmitted to a destination terminal and transmits a radio signal to a plurality of destination terminals by a space multiplex method. The communication device includes: a determination unit which determines the size of the first fundamental signal to be a value of one side of a basic grating determined in accordance with the modulation signal of the first information signal and multiplied by N (a real number not smaller than 1); an addition unit which adds to the first information signal, a first permutation signal obtained by multiplying the first fundamental signal by an integer; and a multiplication unit which multiplies the first information signal added by the first permutation signal, by a weight.
