FPGA Implementation of Viterbi Algorithm for Decoding of Convolution Codes

Abstract: Convolutional code 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 noisy channel. The block codes can be applied only for the block of data. The Convolutional coding has an advantage over the block codes in that it can be applied to a continuous ...

Fpga Implementation of a Vedic Convolution Algorithm

In digital signal processing convolution is a fundamental computation that is ubiquitous in many application areas. In order to compute convolution of long sequence, Overlap-Add method (OLA) and Overlap-Save method (OLS) methods are employed. In this paper, block convolution process is proposed using a multiplier architecture based on vertical and crosswise algorithm of Ancient Indian Vedic Mat...

IMPLEMENTATION OF LDPC USING MIN - SUM DECODING ALGORITHM Maheshwari

In storage system Low-density parity-check (LDPC) codes are used because the performance of error correction is very close to Shannon limit for large block lengths. In this paper LDPC decoder using min-sum algorithm is proposed. The inter-connect complexity is reduced by restricting the extrinsic message length to 2 bits and also simplifies the check node operation by this decoder. The increase...
