Interference is usually viewed as an obstacle to communication in wireless networks, so we developed a new methodology to quantize the channel coefficients in order to realize interference alignment onto a lattice. Our channel model is the same from the compute-and-forward strategy. In this work, we are going to explicit one example of channel quantization, which is related to the dimension 4 (real) or 2 (complex), and we will make use of the binary cyclotomic field Q(ξ8), where ξ8 is the 8-th root of unity.
The authors propose an n-dimensional interleaving technique which spreads a cluster of errors having a quasicircular shape. Consequently simple one-dimensional random-error-correcting codes can be used to correct this kind of cluster instead of the more complex n-dimensional burst-errorcorrecting codes. Moreover let p ≥ 2 be a positive integer, whenever n = 1 mod 3, the corresponding n-dimensional interleaving technique provides a perfect code. Also, whenever n = 3p − 2 = 1 mod 3, the corresponding ndimensional interleaving technique provides neither a perfect code nor a quasiperfect code.
Through algebraic number theory and Construction $A$ we extend an algebraic procedure which generates complex lattice codes from the polynomial ring \mathbb{F}_{2}[x]/(x^{n}-1), where \mathbb{F}_{2}=\{0,1\}, by using ideals from the generalized polynomial ring \frac{\mathbb{F}_{2}[x,\frac{1}{2}\mathbb{Z}_{0}]}{((x^{\frac{1}{2}})^{n}-1)} through the ring of integers $\mathcal{O}_{\mathbb{L}}$ of the cyclotomic field \mathbb{L}=\mathbb{Q}(\zeta_{2^{s}}), where \zeta_{2^{s}} is a 2^{s}-th root of the unit, with s2.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
