Zusammenfassung: | To improve a transmission efficiency when performing a MIMO transmission using an SC-FDE system.SOLUTION: In a pilot signal insertion part 15-1 of a transmission device 1, two continuous UWs or null data are arranged on a diagonal line against a symbol sequence of a block that is the same number of the number of transmission (A), a pilot signal group is constructed by null data (B), the number of pilot signal symbols is powers of 2 (C), the number of MIMO detection range symbols SS is powers of 2, and the following equation is satisfied: SS=(a+b)×d+c×(2×d-1) when a is the number of MIMO block number symbols, b is the number of data symbols, c is the number of pilot signal symbols, and d is the number of MIMO transmissions (D), and the pilot signal is inserted into a predetermined position so that it has a block construction that satisfies the condition that the two continuous pilot signals contained in the first block of a detection object block are the same (E).SELECTED DRAWING: Figure 2
【課題】SC-FDE方式を用いたMIMO伝送を行う際に、伝送効率を向上させる。【解決手段】送信装置1のパイロット信号挿入部15-1は、送信数と同じ数のブロックのシンボル系列に対し、2つの連続するUWまたはヌルデータが対角線上に配置され(A)、パイロット信号群がUW及びヌルデータから構成され(B)、パイロット信号シンボル数cが2の累乗であり(C)、MIMO検出範囲シンボル数SSが2の累乗であり、aをMIMOブロック番号シンボル数、bをデータシンボル数、cをパイロット信号シンボル数、dをMIMO送信数として、SS=(a+b)×d+c×(2×d-1)であり(D)、検出対象ブロックの1番目のブロックに含まれる2つの連続するパイロット信号が同じである(E)条件を満たすブロック構成となるように、パイロット信号を所定の位置に挿入する。【選択図】図2 |
