Reduced Complexity Sphere Decoding Using Forcing Rules

WebA remarkable algorithm for CVP stems from Fincke and Phost (FP) [8], which is well-known as sphere decoding (SD) in communication theory [9], [10]. The FP algorithm only tests the lattice points lying inside a hypersphere. In wireless communication, SD ﬁrst appeared in [11] on lattice code decoding. Since then, SD has gained popularity in WebApr 29, 2024 · In a sense, the term “sphere decoding” is a misnomer as no “decoding” actually takes place. Decoding implies that error encoding has been applied to the source information bits, but this is not a requirement for the sphere decoder. As such, some authors have preferred the term “sphere detection”. jci broye

Decode input using sphere decoder - MATLAB - MathWorks France

In CVP, a basis of a vector space V and a metric M (often L ) are given for a lattice L, as well as a vector v in V but not necessarily in L. It is desired to find the vector in L closest to v (as measured by M). In the -approximation version CVPγ, one must find a lattice vector at distance at most . The closest vector problem is a generalization of the shortest vector problem.
