PROBLEM TO BE SOLVED: To enhance the throughput of an uplink.SOLUTION: A blocking/OQAM mapping section 304 blocks the symbols of a single carrier FDMA, and performs OQAM mapping (OQAM conversion) of the symbols thus blocked, thus obtaining an FTN symbol block subjected to high density multiplexing and allowing interblock interference. An FTN mapping section 305 performs reblocking by superposing and multiplexing the FTN symbol blocks to the same temporal sections as those of the blocks before FTN mapping. A DFT section 306 obtains a symbol subjected to high density multiplexing, by converting the reblocked symbols into a frequency region signal, for each block. |
