WebOct 7, 2024 · Sparse code multiple access (SCMA) is a promising multiuser communication technique for the enabling of future massive machine-type networks. Unlike existing codebook design schemes assuming uniform power allocation, we present a novel class of SCMA codebooks which display power imbalance among different users for downlink … WebGaussian and binary Hamming cases.

WebSep 1, 2024 · Persistent homology is a rigorous mathematical theory that provides a robust descriptor of data in the form of persistence diagrams (PDs) which are 2D multisets of points. Their variable size makes them, however, difficult to combine with typical machine learning workflows. In this paper we introduce persistence codebooks, a novel … WebApr 6, 2024 · We apply this method for the cases of Gaussian and binary codebooks and obtain two achievability bounds. The first bound is very close to Polyanskiy's bound but does not lead to any improvement. At the same time, the numerical results show that the bound for the binary case practically coincides with the bound for the Gaussian codebook.

In particular, it must be long enough for the fading to reflect its ergodic nature, i.e. the symbol time T must be much larger than the coherence time Tcoh, defined to be
WebAdditive white Gaussian noise (AWGN) is a basic noise model used in information theory to mimic the effect of many random processes that occur in nature. The modifiers denote … WebGaussian codebook and white Gaussian noise constitute a unique saddle point. In [11], [12] (and references therein) it was shown that a Gaussian codebook and minimum Euclidean distance decoding achieves rate 1 2 log(1 + P=N 0) under an average power constraint. Therefore, for average signal and noise power constraints the max-
WebCommon visual codebook generation methods used in a bag of visual words model, for example, k-means or Gaussian Mixture Model, use the Euclidean distance to cluster features into visual code words. However, most popular visual descriptors are histograms of image measurements. It has
