"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”. " - Sphere decoding matlab
