使用错误校正卷积代码和规格不变的旋转玻璃模型之间的对应关系用于表明恢复原始消息的最佳方法是通过在有限温度$ {MATHIT {T}} _ {Mathit {N}} $上解码（p）g0，其中p是通道噪声的强度和$ {mathit {t}} _ {Mathit {n}} $（p） Nishimori温度。这改善了T = 0最大似然性viterbi解码算法的检索性能而没有增加其计算复杂性。数值模拟支持该理论。
The correspondence between error-correcting convolution codes and gauge invariant spin-glass models is used to show that the optimal way to recover the original message is by decoding at a finite temperature ${mathit{T}}_{mathit{N}}$(p)g0, where p is the strength of the channel noise and ${mathit{T}}_{mathit{N}}$(p) the Nishimori temperature. This improves upon the retrieval performance of the T=0 maximal likelihood Viterbi decoding algorithm without increasing its computational complexity. Numerical simulations support the theory.
