WebJan 27, 2024 · 2.1 Preliminaries on Group Rings. Let G be a multiplicative group and let R be a ring. The group ring of G over R, which is denoted by R[G] (or simply RG), is the set of mappings \(f : G\rightarrow R\) of finite support. Footnote 1 A group ring is a free module and at the same time a ring. As a free module, its ring of scalars is the given ring R, and its … WebMar 8, 2024 · Here, we describe space-time block codes with the help of the first and most well-known example: the Alamouti code. Example from Grade 6. You can understand Alamouti space-time code easily if you can solve the following set of equations for two numbers s1 and s2. 2 ⋅ s1 + 7 ⋅ s2 = − 1 4 ⋅ s1– 5 ⋅ s2 = 17.
