Rujan关于纠错码的猜想得到了证明。当信号在特定的有限温度下解码时，通过噪声信道传输的信号的解码误差呈现最小值。将该有限温度解码与对应于T=0情况的传统最大似然解码进行比较。自旋玻璃理论中的规范变换方法在这个论证中很有用。
The conjecture of Rujan on error-correcting codes is proven. Errors in decoding of signals transmitted through noisy channels assume the smallest values when signals are decoded at a particular finite temperature. This finite-temperature decoding is compared with the conventional maximum likelihood decoding which corresponds to the T =0 case. The method of gauge transformation in the spin glass theory is useful in this argument.
