The CTE-301 Series Bit Error-Rate Tester (BERT) provides basic functional end-to-end testing of a PCM link or processing equipment. The CTE-301 was designed for use in production testing....

The Viterbi decoder itself is the primary focus of this tutorial. Perhaps the single most important concept to aid in understanding the Viterbi algorithm is the trellis diagram. The figure below shows the trellis diagram for our example rate 1/2 K = 3 convolutional encoder, for a 15-bit message:.....

The purpose of this project is to introduce the basic ideas behind the Viterbi algorithm. In particular, its application in Text Recognition is analyzed by means of the use of contextual information. A Java implementation was made in order to illustrate how the Viterbi algorithm works......

In its basic form, Viterbi decoding (or forward dynamic programming) is an efficient, recursive algorithm that performs an optimal exhaustive search.  A convolutional encoder and Viterbi decoder can be used together to provide error correction over a noisy channel e.g., communications channel......
