摘要
本文讨论了分组码组合编码调制中最常见码—陪集码的归一化重量分布多项式.导出了采用部分正交码时这一多项式的计算公式.例子表明在适当选取正交部分时,归一化重量分布多项式的计算可以大大简化.
Normalized weight distribution polynomial was discussed for the coset codes which are most popular in combining block eods with coded modulation.Formulas for computing the polynomial by partial orthogonal method were developed in this paper.Examples show that the computing complexity can be largely reduced by choosing suitable orthogonal parts of the code.
