FPGA Implementation of Viterbi Decoder
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 کاملDesign of a super-pipelined Viterbi decoder
This paper presents a novel super-pipelined VLSI architecture for Viterbi decoders. This architecture is capable of achieving high throughput in an area-efficient manner and hence it is an attractive architecture for implementing the Viterbi decoder where a large constraint length and high throughput rate are required. The throughput can be linearly increased by increasing the number of basic p...
متن کاملFPGA 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 ...
متن کاملA Novel Methodology to Implement Viterbi Decoder Using FPGA
Bandwidth and power is the most important parameter in every communication system. So the maximum utilization of bandwidth and minimum useful usage of power is achieved with error detection and correction methods. In satellite &space communication channel capacity is degraded as a result of Additive White Gaussian Noise, which are mostly random. Convolutional encoder with Viterbi decoder is a r...
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...
