Learning Joint Detection, Equalization and Decoding for Short-Packet Communications

Iterative Equalization and Decoding Scheme for Underwater Acoustic Coherent Communications

Digital communications through underwater acoustic (UWA) channels differ from those in other media, such as radio channels, due to the high temporal and spatial variability of the acoustic channel which make the available bandwidth of the channel limited and dependent on both range and frequency. In order to overcome disadvantage factors and maximize performance to conduct real-time information...

A primer on equalization, decoding and non-iterative joint equalization and decoding

In this article, a general model for non-iterative joint equalization and decoding is systematically derived for use in systems transmitting convolutionally encoded BPSK-modulated information through a multipath channel, with and without interleaving. Optimal equalization and decoding are discussed first, by presenting the maximum likelihood sequence estimation and maximum a posteriori probabil...

Comparison of structures for joint equalization and decoding

In this paper, we compare two structures for combined Equalization/Detection of linear codes over frequency selective channels. The structures come from different families of codes: convolutionnal codes on one hand and parity check block codes on the other hand. First, we show that the joint receiver process corresponds to an iterative belief propagation schedule on graphical representations. T...

Improved Receivers for Digital High Frequency Communications: Iterative Channel Estimation, Equalization, and Decoding (Adaptive Turbo Equalization)

We address the problem of improving the throughput and the availability of digital communications in the High Frequency (HF, 3-30 MHz) band. In standardized military waveforms, the data is protected by an error-correcting code (ECC), and the code bits are shuffled by an interleaver and mapped onto a signal constellation for modulation onto a single carrier. Training sequences are multiplexed in...
