Lattice’s Block Convolutional Encoder IP core is a parameterizable core for convolutional encoding of continuous or burst input data streams. The core allows different code rates and constraint ...

Viterbi algorithm is used in the Viterbi decoder for decoding a bit stream that has been encoded using FEC based on a Convolutional code. Below Figure shows the block diagram of Viterbi decoder. It ...

Abstract: From a linear block code B over the Galois ring GR(4, m) with a k times n generator matrix and minimum Hamming distance d, a rate-k/n convolutional code over the ring Z 4 with squared ...

Figure 6 shows the state diagram for r = 1/3, constraint length L = 3 convolutional code with the generator matrix G = [5 7 7]. The state diagram does not change when the generator matrix is shifted, ...

Abstract: From a linear block code B over the Galois ring GR(4, to) with a k x n generator matrix and minimum Hamming distance d, a rate-k/n convolutional code over the ring Z 4 with squared Euclidean ...
