Fuchsian codes with arbitrarily high code rates
(2016-01-01)
Article
Accés obertRecently, Fuchsian codes have been proposed in Blanco-Chacon et al. (2014) [2] for communication over channels subject to additive white Gaussian noise (AWGN). The two main advantages of Fuchsian codes are their ability ... -
Hyperbolic uniformizations throught computations on ternary quadratic forms
(2013)
Text en actes de congrés
Accés obertOrders in indefinite quaternion algebras provide Fuchsian groups acting on the Poincare half-plane, used to construct the associated Shimura curves. We explain how, by using embedding theory, the elements of those Fuchsian ... -
Nonuniform Fuchsian codes for noisy channels
(2014-11-01)
Article
Accés obertWe develop a new transmission scheme for additive white Gaussian noisy (AWGN) channels based on Fuchsian groups from rational quaternion algebras. The structure of the proposed Fuchsian codes is nonlinear and nonuniform, ...
