PROBLEM TO BE SOLVED: To provide a signal creation device which increases compressibility of a data signal rather than the prior arts, and a signal detection device.SOLUTION: At a transmission side, a Kronecker product of a row vector for a pilot and a pilot signal, and a Kronecker product of a vector for data and transmission data are calculated and transmission signals KS0-KS2 are created for each virtual channel in transmission signal creation sections 11-13. In a data convolution addition section 15 for the virtual channel, a signal convolving data for virtual channel generation into the transmission signals KS0-KS2 is added and transmitted via a transmission section 17 and an antenna 18. At a reception side, the inputted signal is branched. While using a signal convolving separate reception side virtual channel characteristics into the branched signals, data are estimated and a signal is detected.SELECTED DRAWING: Figure 9 |
