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 ...
متن کاملDecoder FPGA Implementation
—The non-binary Low Density Parity Check (LDPC) codes over Galois Fields GF(q = 2) have evolved from the binary LDPC codes that are today an industry standard for channel coding. The performance of short block length codes is significantly higher for non-binary LDPC, at the cost of increased decoding complexity. The efficient decoder hardware implementation is still a challenging task. Most of...

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 کاملImplementation of a RANLUX Based Pseudo-Random Number Generator in FPGA Using VHDL and Impulse C
Monte Carlo simulations are widely used e.g. in the field of physics and molecular modelling. The main role played in these is by the high performance random number generators, such as RANLUX or MERSSENE TWISTER. In this paper the authors introduce the world’s first implementation of the RANLUX algorithm on an FPGA platform for high performance computing purposes. A significant speed-up of one ...
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...
