Let X, Y, and K be the stochastic variables associated with x, Thus we want to minimize P under the condition (6), which can y, and k. Let H(y) be the entropy of Y when nothing is known be rewritten as about k. Let H:)(y) be the conditional entropy of Y for a given x, after i pairs (3,~~) have been intercepted. Let H(k) be the entropy of K. Smce f(x, k) is an unknown function if k is unknown, this equation from [2] is valid:

On Equivalent Convolutional Encoders
"... encoder as a linear sequential circuit with k inputs and one output is proposed. We discuss the classical definition of equivalent codes (type 1 equivalence) and propose the definition of encoders that generate different codes but with the same code spectrum (type 2 equivalence). We conclude with so ..."

Blind Identification of Convolutional Encoder Parameters
"... This paper gives a solution to the blind parameter identification of a convolutional encoder. The problem can be addressed in the context of the noncooperative communications or adaptive coding and modulations (ACM) for cognitive radio networks. We consider an intelligent communication receiver whi ..."

Convolutional Encoding of Some Binary Quadratic Residue Codes
"... Abstract—In this paper, the optimal convolutional encoding for the five quadratic residue (QR) codes are investigated. Simulation results show that the smallest constraint length K =4(respectively, K =4, 8, 11, 14) is convolutionally encoded for the QR code ..."
