Abstract: In the case where an e-mail transmission to a plurality of persons is to be performed at one time, e-mail erroneous transmission due to a setting error of an e-mail address or the like can be prevented from occurring. In an e-mail transmitting and receiving apparatus, an address storing portion 113 which stores a plurality of e-mail addresses; an input operating portion 101 in which, during e-mail creation, a plurality of destination addresses are input; an attribute discriminating unit 120 which discriminates attribute information of the plurality of destination addresses while referring to the address storing portion; and an informing unit 123 are included. In the case where the attribute discriminating unit discriminates that a destination address having different attribute information exists in the plurality of destination addresses, the informing unit shows a user that an unusual setting is contained.

Abstract: A data distributor distributes interleaved data strings and outputs them to puncturing sections in a frame unit. A puncturing instructing section refers to a rate matching table to output information on data to be punctured to a plurality of puncturing sections. Each puncturing section performs the judgment processing on whether puncturing is to be performed only for parity bits according to the rule of an arrangement of information bits and parity bits for each frame and then performs puncturing. This enables to reduce processing for turbo-coded data after interleave processing and to perform light-load rate matching.

Abstract: A data distributor (101) distributes interleaved data strings and outputs them to puncturing sections (103) to (106) in a frame unit. A puncturing instructing section (102) refers to a rate matching table (107) to output information on data to be punctured to a puncturing section (103), a puncturing section (104), a puncturing section (105), and a puncturing section (106). The puncturing section (106) performs the judgment processing on whether puncturing is to be performed only for parity bits according to the rule of an arrangement of information bits and parity bits for each frame and then performs puncturing. This enables to reduce processing for turbo-coded data after interleave processing and to perform light-load rate matching.
