Abstract: Embodiments of the present invention provide a method and a decoder for processing decoding. The method includes: acquiring a combined generator matrix Gcom of a Turbo code generator matrix Gturbo and a cyclic redundancy check CRC generator matrix Gcrc, and acquiring a log likelihood ratio sequence outputted by a Turbo code decoder; and performing CRC-assisted iterative ordered statistics decoding of a Turbo code by using the combined generator matrix Gcom and the log likelihood ratio sequence, so as to obtain a decoding processing result. A decoding performance gain can be improved by using the method and the device for decoding a Turbo code provided in the embodiments of the present invention.

Abstract: A method for estimating a block error rate and a communication device are applied to the field of communications technologies. The method for estimating a block error rate includes: decoding N received coded code blocks to obtain multiple posterior probabilities APPs, where N is a natural number greater than 1; obtaining, according to the multiple posterior probabilities APPs and a preset policy, a result indicating that the decoding of each coded code block is correct or incorrect, where the preset policy includes: when a sum of absolute values of the multiple APPs is greater than or equal to a preset threshold, the decoding is correct; and obtaining a decoding block error rate according to a result indicating whether the decoding of the N coded code blocks is correct. In this way, the estimation of a decoding block error rate is implemented.

Abstract: A glass substrate manufacturing method of the present invention comprises forming a multi-porous structure layer which comprises nano-size pores at a surface of a glass substrate by etching the surface of the glass substrate with hydrofluoric (HF) acid or an etchant substituting for fluoride. Unlike related art methods, the glass substrate forms no additional coating layer, uses no harmful chemical material, and is given anti-reflection, anti-fogging, and super-hydrophilic characteristics through a simple process at a relatively low temperature. The glass substrate is effectively applied to various applications requiring high light transmission such as a protective filter for a display device, a solar cell, a mobile communication device, glass of a building structure, and an optical element lens.
