چکیده
The aim of the project is execution of Viterbi algorithm applying HDL coding. The overall objective is to clearly understand the Hidden Markov model and Viterbi Decoder, to evaluate the basic functionalities and steps involved in Viterbi algorithm, to project on the implementation of Viterbi algorithm through HDL code and finally to critically analyze the results obtained through HDL code. The main purpose of this study is to yield the gains obtained by the developers with the usage of Viterbi algorithm. This project not only helps the students related to the communications but it also helps the people who are in the field of decoders as it is one of the efficient method for reducing the errors while communication procedure is in advance. Here, HDL code is used in order to implement the Viterbi algorithm in a proper way. Apart from students and the business people, one can easily understand and analyze the Viterbi algorithm concepts and can gain more knowledge on the tools that are used in this project.

It is well known that the Viterbi decoder (VD) is the dominant module determining the overall power consumption of TCM decoders. High-speed, low-power design of Viterbi decoders for trellis coded modulation (TCM) systems is presented in this paper. We propose a precomputation architecture incorporated with -algorithm for VD, which can effectively reduce the power consumption without degrading t...

High speed Viterbi decoder design for trellis coded modulation (TCM) is presented in this paper. It is well known that the Viterbi decoder (VD) is the dominant module for determining shortest path. We propose a pre-computation architecture incorporated with T-algorithm for VD, which can find the shortest path without degrading the decoding speed much. A general solution to derive the optimal pr...
متن کاملAdapting the strongly-connected trellis concept for use with trellis-coded modulation
The strongly-connected trellis was originally proposed by Chang and Yao as a way of increasing the efficiency of Viterbi decoders implemented on locally-connected parallel processor arrays. Originally, this concept was derived with binary convolutional codes in mind. Its adaptation to TCM is non-trivial due to the presence of parallel branches in the trellis. The method we propose utilizes a mo...
