Implementation of Convolution Encoder and Viterbi Decoder for Constraint Length 7 and Bit Rate 1 / 2
Convolutional codes are non blocking codes that can be designed to either error detecting or correcting. Convolution coding has been used in communication systems including deep space communication and wireless communication. At the receiver end the original message sequence is obtained from the received data using Viterbi decoder. It implements Viterbi Algorithm which is a maximum likelihood a...
متن کاملDesign and Implementation of Convolution Encoder and Viterbi Decoder
Data transmissions over wireless channels are affected by attenuation, distortion, interference and noise, which affect the receiver’s ability to receive correct information. Convolution encoding with Viterbi decoding is a powerful method for forward error correction. Convolution encoders and Viterbi decoders play an important role in digital communication especially, when channel is noisy and ...
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 کاملAn Experimental Implementation of Convolution Encoder and Viterbi Decoder by FPGA Emulation
Error-correcting convolution codes prove to be a powerful methodology to limit the effects of noise in digital data transmission. Convolution Encoding with Viterbi decoding is a powerful Forward Error Control (FEC) technique that is a proven mechanism in which the transmitted signal remains uncorrupted mainly by Additive white Gaussian Noise residing inside a channel. In this work, a Convolutio...
