Patent ID: 8867633

Claim:
A transmitting method that transmits a plurality of signals generated by calculating a Kronecker product of each of sequences that are N (N is a natural number equal to or larger than 3) row vectors or column vectors of an Nth order DFT matrix, or of each of N sequences of a ZCCZ sequence set, and a pilot signal and transmission data having a length M (M is a natural number equal to or larger than 2), said N sequences being f 0 , f 1 , f 2 , . . . f N-1 , said transmitting method comprising the steps of: allocating P (P is a natural number equal to or larger than 2) sequences out of the N sequences to pilot sequences for transmitting pilot signals, and N−P sequences to data sequences for transmitting transmission data; preparing Q (Q is a natural number equal to or larger than 2 and equal to or smaller than P) pieces of virtual channel generation data configured by two-phase signals, four-phase signals, or complex signals; generating R (R is a natural number equal to or larger than 1 and equal to or smaller than Q) transmission signals each of which comprises a Kronecker product of one of the pilot sequences and a pilot signal and a Kronecker product of the data sequences and transmission data; and convoluting each of the generated R transmission signals with one separate piece of the virtual channel generation data and transmitting the convoluted signals.
