Trellis Decoding And Applications For Quantum Error Correction
… representations of error-correcting codes called trellises are a crucial tool in classical coding theory, establishing both theoretical properties and performance metrics for practical use. The idea was extended to quantum error-correcting codes by Ollivier and Tillich in 2005. Here, we use their …

Error -Correcting Codes on Graphs: Lexicodes, Trellises and Factor Graphs
… In the first technique, which is based on decoding with a layered graph known as a trellis, we examine generalization of heuristically good codes called lexicodes. We propose and analyze a method for designing generalized lexicodes that minimize or constrain various trellis decoding …

Multi-dimensional direct-sequence spread spectrum multiple-access communication with adaptive channel coding
… Algorithm(SOVA) decoder [39] structure for the trellis decoding of the binary linear block codes [3, 41-50], as well as binary convolutional codes mentioned, over realistic MU frequency selective channel conditions. This application will grant the system the ability to sense changes in …

Iterative Decoding and Channel Estimation over Hidden Markov Fading Channels
… Markov fading models within an iterative (turbo) decoding framework. Of particular importance is the problem of channel estimation, which is vital for realizing the large coding gains inherent in turbo coded schemes. This thesis shows that a Markov fading channel (MFC) can be conceptualized as a …
