block code length 中文意思是什麼
block code length
解釋
分組碼長-
Absolute minimal trellis complexities of extended codes and their dual codes of two types of linear block codes whose code length is odd are given
給出了兩類奇數碼長線性分組碼的擴展碼及其對偶碼的絕對最小網格圖復雜度。 -
Ldpc code belongs to the linear block code which is encoded by the information sequence multiplies generator matrix. although the parity - check matrix of ldpc code is sparse, the generator matrix is not. the encoding complexity of it is linearly proportional to the square of code length
Ldpc碼屬于線性分組碼,線性分組碼的通用編碼方法是由信息序列根據碼的生成矩陣來求相應的碼字序列,盡管ldpc碼的校驗矩陣是非常稀疏的,但它的生成矩陣卻並不稀疏,這使得其編碼復雜度往往與其碼長的平方成正比。
