An Efficient CDMA System Based on Reed Solomon Code (RS Code)

, 2018
Accurate Error control is a necessary constraint for the design of Cellular Code Division Multiple Access (CDMA) systems. The Block codes can correct twice as many erasures as errors; the coded performance can be improved. In this paper, we propose ‘An efficient Error correcting coding in CDMA systems. The system performance is improved using FEC based

A simplified procedure for correcting both errors and erasures of a Reed-Solomon code using the Euclidean algorithm [PDF]

It is well known that the Euclidean algorithm or its equivalent, continued fractions, can be used to find the error locator polynomial and the error evaluator polynomial in Berlekamp's key equation needed to decode a Reed-Solomon (RS) code.

Nonlinear, nonbinary cyclic group codes [PDF]

New cyclic group codes of length 2(exp m) - 1 over (m - j)-bit symbols are introduced. These codes can be systematically encoded and decoded algebraically.

Fast transform decoding of nonsystematic Reed-Solomon codes [PDF]

A Reed-Solomon (RS) code is considered to be a special case of a redundant residue polynomial (RRP) code, and a fast transform decoding algorithm to correct both errors and erasures is presented.

Learn to Interpret Atari Agents

, 2019
Deep Reinforcement Learning (DeepRL) agents surpass human-level performances in a multitude of tasks. However, the direct mapping from states to actions makes it hard to interpret the rationale behind the decision making of agents.

MDR codes and self-dual codes on Cartesian product codes

Tongxin xuebao, 2010
A Cartesian product code of the linear codes C1 , , C s in 1 , ,Z r Z rs was defined. According to the theorem of submodulo isomorphism, the relationship between the rank of the Cartesian product code C1 × C 2 × × Cs over Z r1 × Z r2 × × Zrsand C1 , C 2,

Optimal Codes for the Burst Erasure Channel [PDF]

Deep space communications over noisy channels lead to certain packets that are not decodable. These packets leave gaps, or bursts of erasures, in the data stream. Burst erasure correcting codes overcome this problem.
