NON-ORTHOGONAL SIGNAL-BASED OPTICAL COMMUNICATION SYSTEMS USING FUZZY LEARNING FOR INTERFERENCE CANCELLATION [PDF]
Proceedings on Engineering Sciences, 2023 Non-orthogonal signal-based systems are a type of communication system that uses signals that are not mutually perpendicular (i.e., not orthogonal) to transmit information.

Combining coded signals with arbitrary modulations in orthogonal relay channels [PDF]
, 2008 We consider a relay channel for which the following assumptions are made. (1) The source-destination and relay-destination channels are orthogonal (frequency division relay channel). (2) The relay implements the decode-and-forward protocol.

L-Orthogonal Signal Transmission and Detection [PDF]
IEEE Transactions on Communications, 1972 This paper investigates the detail capabilities and performance characterization of systems that employ L -orthogonal signaling techniques. L -orthogonal signals represent a unified set of signals wherein the polyphase and orthogonal (biorthogonal) signal sets are included as special cases.

Theoretical performance analysis of the W-ABORT detector [PDF]
, 2008 In a recent paper we introduced a modification of the adaptive beaniformer orthogonal rejection test (ABORT) for adaptive detection of signals in unknown noise, by supposing under the null hypothesis the presence of signals orthogonal to the nominal ...

An ABORT-like detector with improved mismatched signals rejection capabilities [PDF]
, 2008 In this paper, we present a GLRT-based adaptive detection algorithm for extended targets with improved rejection capabilities of mismatched signals. We assume that a set of secondary data is available and that noise returns in primary and secondary data ...

Low‐complexity BER computation for coherent detection of orthogonal signals
Electronics Letters, 2021 The bit error rate (BER) computation for coherently detected orthogonal signals in additive white Gaussian noise requires numerical integration, which can be cumbersome in low‐complexity devices. Here, a BER computation approach that circumvents the need

Phosphoregulated orthogonal signal transduction in mammalian cells [PDF]
Nature Communications, 2020 AbstractOrthogonal tools for controlling protein function by post-translational modifications open up new possibilities for protein circuit engineering in synthetic biology. Phosphoregulation is a key mechanism of signal processing in all kingdoms of life, but tools to control the involved processes are very limited.
