Rateless Coding over Wireless Relay Networks Using Amplify/Decode and Forward Relays [PDF]
Journal of Electrical and Computer Engineering Innovations, 2013 In this paper two different rateless transmissionschemes are developed. In the proposed scheme, relay node candecode and forward the message to the destination if they areable to decode it, or amplify and forward the message to thedestination.

Bit‐Error‐Rate Analysis of Raptor Codes over Rician Fading Channels
Journal of Electrical and Computer Engineering, Volume 2020, Issue 1, 2020., 2020 The bit‐error‐rate expressions of nonsystematic Raptor (NR) codes and systematic Raptor (SR) codes over Rician fading channels are first derived using a Gaussian approximation (GA) approach. These BER expressions provide a significant reduction in computational complexity for analyzing system performance when compared with simulation and discretized ...

An Efficient Design of Systematic Rateless Codes
Wireless Communications and Mobile Computing, Volume 2020, Issue 1, 2020., 2020 The asymptotic performance of systematic rateless codes is first analysed using Gaussian approximation (GA) based on mutual information, which provides more accurate decoding thresholds than the method based on message mean. A modified linear program (LP) algorithm is proposed, where two key parameters are precomputed to efficiently search degree ...

Analysis and Design of Systematic Rateless Codes in FH/BFSK System with Interference
Mobile Information Systems, Volume 2020, Issue 1, 2020., 2020 The asymptotic analysis of systematic rateless codes in frequency hopping (FH) systems with interference is first provided using discretized density evolution (DDE) and compared with the traditional fixed‐rate scheme. A simplified analysis with Gaussian assumption of initial message is proposed in the worst case of interference, which has much lower ...
