  • Patent number: 11277226
    Abstract: A transmitter apparatus wherein a simple structure is used to successfully suppress the degradation of error rate performance that otherwise would be caused by fading or the like. There are included encoding parts that encode transport data; a mapping part that performs such a mapping that encoded data sequentially formed by the encoding parts are not successively included in the same symbol, thereby forming data symbols; and a symbol interleaver that interleaves the data symbols. In this way, a low computational complexity can be used to perform an interleaving process equivalent to a bit interleaving process to effectively improve the reception quality at a receiving end.

  • Patent number: 11254148
    Abstract: A medium processing apparatus includes a printer, a supporting member having a sheet-like shape and configured to support a discharged medium, and a winding unit configured to wind the supporting member and move with respect to the printer. The winding unit has a first case and a second case that rotatably support a winding shaft, and a placement portion placed at a flat surface. The first case and the second case in a state where axis lines of respective bearing portions that support the winding shaft are aligned with each other and in a state of being held so as to be mutually non-rotatable in a plane orthogonal to an axis line of the winding shaft, and when the winding unit is installed on a flat surface, the placement portion contacts the flat surface.
