    • A method and apparatus for Viterbi detector state metric re-normalization. The method includes fabricating a Viterbi detector (138) having a predetermined number of states, wherein the Viterbi detector (138) stores a state metric value and a branch metric value for each state, and wherein the Viterbi detector (138) implements a trellis diagram. The method includes constructing a Viterbi detector (138) which can support a state metric value having g+h′ number of bits. The number of bits needed to represent the branch metric value is represented by (g) and the additional number of bits needed to represent the state metric value is represented by (h′). The additional number of bits (h′) is less than the additional number of bits (h) determined using the following inequality: 2h−1−h≧K−1, wherein K represent the constraint length of the trellis diagram.
    • 一种用于维特比检测器状态度量重新归一化的方法和装置。 该方法包括制造具有预定数量状态的维特比检测器(138),其中维特比检测器(138)存储每个状态的状态度量值和分支度量值,并且其中维特比检测器(138)实现格状图 。 该方法包括构造可支持具有g + h'比特数的状态度量值的维特比检测器(138)。 表示分支量度值所需的位数由(g)表示,表示状态量度值所需的附加位数由(h')表示。 附加位数(h')小于使用以下不等式确定的附加位数(h):2 -h> = K-1,其中K表示网格图的约束长度 。
