FPGA Based Efficient Implementation of Viterbi Decoder
It is well known that data transmissions over wireless channels are affected by attenuation, distortion, interference and noise, which affect the receiver’s ability to receive correct information. Convolutional encoding with Viterbi decoding is a powerful method for forward error detection and correction. It has been widely deployed in many wireless communication systems to improve the limited ...

Convolutional encoding with Viterbi decoding is a powerful method for forward error correction. It has been widely deployed in many wireless communication systems to improve the limited capacity of the communication channels. The Viterbi algorithm, which is the most extensively employed decoding algorithm for convolutional codes. In this paper, we present a field-programmable gate array impleme...
متن کاملFPGA Implementation of Convolutional Encoder And Hard Decision Viterbi Decoder
In this paper, we concern with designing and implementing a convolutional encoder and Viterbi decoder which are the essential block in digital communication systems using FPGA technology. Convolutional coding is a coding scheme used in communication systems including deep space communications and wireless communications. It provides an alternative approach to block codes for transmission over a...
متن کاملFPGA Implementation of Convolution Encoder and Viterbi Decoder
The data transmission in any wireless communication system is affected by attenuation, interference, noise and distortion which affect the receiver’s ability to receive the correct information. The Convolution encoder and viterbi decoder are good forward error detection and correcting codes for a channel, which is affected by noise. The convolution encoder is used for correction of errors at th...
متن کاملFPGA Implementation of Viterbi Decoder using Trace back Architecture
Error correction is an integral part of any communication system and for this purpose, the convolution codes are widely used as forward error correction codes. For decoding of convolution codes, at the receiver end Viterbi Decoder is being employed. The parameters of Viterbi algorithm can be changed to suit a specific application. The high speed and small area are two important design parameter...
