  • Patent number: 10103750
    Abstract: An error correction decoding apparatus includes column operators 201 and row operators 211 to 213 provided respectively in accordance with the columns and rows of a check matrix of an LDPC code. A received LLR (log-likelihood ratio) of a received sequence is input into the column operators 201 together with row LLRs from the row operators 211 to 213, whereupon the column operators 201 calculate a total value z1 of the received LLR of the received sequence and the row LLRs from the row operators 211 to 213. The row operators 211 to 213 hold operation results relating to row LLRs or column LLRs obtained during a previous operation, calculate column LLRs using the total value input from the column operators 201 and the held operation results, calculate row LLRs from the calculated column LLRs, and output the calculated row LLRs to the column operators 201.

  • Publication number: 20180294921
    Abstract: An error correction encoder (10) includes an interleaver circuit (31), encoding circuits (321, 322) and a deinterleaver circuit (33). The interleaver circuit (31) generates, in a standard speed mode, a single series of yet-to-be-coded bit sequences (IL1) on the basis of the bits in plural columns that are arranged at an interval of C columns in a single series of transmission frames, and generates, in a two-times speed mode, two series of yet-to-be-coded bit sequences (IL1, IL2) on the basis of the bits in plural columns that are arranged at an interval of C/2 columns in each of two series of transmission frames. The encoding circuits (321, 322) apply error-correction coding to either the single series of yet-to-be-coded bit sequences (IL1) or the two series of yet-to-be-coded bit sequences (IL1, IL2).

  • Patent number: 9770742
    Abstract: An object to be decontaminated contaminated with radioactive material is introduced into an acid eluting solvent to dissolve the radioactive material. The radioactive material dissolved is concentrated and separated from the eluting solvent in the present method. The object to be decontaminated comprises contaminated soil and contaminated liquid. One or both of the contaminated soil and the contaminated liquid are collected and introduced into the eluting solvent. The radioactive materials and the object to be decontaminated dissolved in the eluting solvent are separated into solid and liquid. The decontaminated soil separated from the eluting solvent is collected. The eluting solvent used for separating the radioactive material and in which radioactive material is dissolved is concentrated.

  • Publication number: 20160362792
    Abstract: A film-forming structure and a film-forming method on a work include closely depositing a thin primary film on a work, the primary film being a suboxide or an oxide including metal and is soft and has insulation properties and corrosion resistance. The primary film is porous film. The work is integrated with the primary film to prevent the primary film from peeling, and thereby improving the workability. The thin secondary film such as a coating is attached to the primary film closely, thereby reducing the amount of paint used. The primary film is integrated with the secondary film to prevent the secondary film from peeling, improving the workability after formation of the secondary film, and thereby forming the primary and secondary films rationally.
