n-ary block codes related to KU-algebras
Journal of Taibah University for Science, 2020 In this paper, n-ary block codes for KU-algebras and their interconnecting properties in terms of block codes have been given. A construction of n-ary block codes for a given KU-algebra is shown, and it is proved that for each n-ary block code K we can ...

Perfect Space–Time Block Codes [PDF]
IEEE Transactions on Information Theory, 2006 In this paper, we introduce the notion of perfect space–time block codes (STBCs). These codes have full-rate, full-diversity, nonvanishing constant minimum determinant for increasing spectral efficiency, uniform average transmitted energy per antenna and

Differential properties of polar codes [PDF]
E3S Web of Conferences, 2023 This paper discusses the features of polar coding as a differential encoder for a binary erasure channel. One of the modern methods of error-correcting coding is polar codes, which has great prospects in the development of current and future wireless ...

On Decoder Ties for the Binary Symmetric Channel with Arbitrarily Distributed Input
Entropy, 2023 The error probability of block codes sent under a non-uniform input distribution over the memoryless binary symmetric channel (BSC) and decoded via the maximum a posteriori (MAP) decoding rule is investigated.

ELIMINATION OF INTERFERENCE WITH WIRELESS MESH NETWORKS THROUGH BINARY SYMMETRICAL CHANNELS
STED Journal, 2023 This paper presents the binary symmetric channel as a common model of the communication channel used in theory of coding and theory of information. Since there is no noise in the channel, the data transmission delay is very small, which is why data can ...

Coded-GFDM for Reliable Communication in Underwater Acoustic Channels
Sensors, 2022 The performance of the coded generalized frequency division multiplexing (GFDM) transceiver has been evaluated in a shallow underwater acoustic channel (UAC). Acoustic transmission is the scheme of choice for communication in UAC since radio waves suffer
