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

A symmetric adaptive visibility graph classification method of orthogonal signals for automatic modulation classification

IET Communications, 2023
Visibility graph methods allow time series to mine non‐Euclidean spatial features of sequences by using graph neural network algorithms. Unlike the traditional fixed‐rule‐based univariate time series visibility graph methods, a symmetric adaptive ...

A Rotated Quasi-Orthogonal Space-Time Block Code for Asynchronous Cooperative Diversity

Entropy, 2012
The rotated quasi-orthogonal space-time block code (RQSTBC) for asynchronous cooperative diversity is proposed in this paper. The source selects half of the symbols from a signal constellation set and the other half of them from that constellation ...

Orthogonal least squares algorithm for training multi-output radial basis function networks [PDF]

, 1991
A constructive learning algorithm for multioutput radial basis function networks is presented. Unlike most network learning algorithms, which require a fixed network structure, this algorithm automatically determines an adequate radial basis function ...
