    • The present invention is a method of determining codeword boundary without marker bits by receiving transmission bits; determining a dual code of a code used to generate the transmission bits; selecting a vector from the dual code; initializing n scoring variables; initializing i=1; initializing z=1; selecting n bits from the transmission bits starting at bit position i; performing a bit-wise AND operation on the vector and the n selected bits; if the result of the bit-wise AND operation contains an even number of ones then assigning a value of zero to the result, otherwise assigning a value of one to the result; setting Sz equal to Sz plus the result of the last step; if z is less than n, incrementing z and i each by 1 and returning to the seventh step, otherwise proceeding to the next step; if z=n, i
    • 本发明是一种通过接收传输比特来确定无标记位的码字边界的方法; 确定用于生成所述传输比特的码的双码; 从双码选择一个矢量; 初始化n个评分变量; 初始化i = 1; 初始化z = 1; 从位位置i开始的传输位选择n位; 对向量和n个选择的比特执行逐位AND运算; 如果逐位AND运算的结果包含偶数个数,则向结果分配一个零值,否则为结果分配一个值; 设置Sz等于Sz加上一步的结果; 如果z小于n,将z和i分别递增1并返回到第七步,否则进行下一步骤; 如果z = n,i
