چکیده
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 the receiver end. This paper presents implementation of convolution Encoder and Viterbi Decoder with a constrained length of 3 and a code rate of 1⁄2 by using virtex-5 FPGA.
