Fiber product`s algebraic geometry code decoding process for communication system, involves decoding compiled algebraic codes, defined on same algebraic curve represented by equation in X and Z

摘要

The process involves decoding compiled algebraic codes defined on a same algebraic curve represented by an equation in X and Z. The equation is obtained by taking mu component algebraic equations of a fiber product. Each one of the component algebraic equations controls the unknown factor X and an unknown factor Y i, where i is chosen between 0 and mu -1. Independent claims are also included for the following: (A) a coded digital signal receiving apparatus (B) a computer system (C) a data storage medium with code instructions of computer program for executing a process for decoding algebraic geometry code (D) computer program with instructions for executing a process for decoding algebraic geometry code.
