Sphere decoding of symbols transmitted in a telecommunication system

摘要

A method for decoding at least one signal, including: receiving the at least one signal, the at least one signal being transmitted by at least one transmitting antenna and received by at least one receiving antenna; defining a sphere having a predetermined radius and being centered on a particular symbol chosen among predetermined symbols forming a lattice constellation of symbols which may be received by the receiving antenna; and producing estimated symbols representative of at least one transmitted symbol carried by the at least one signal and identified among the predetermined symbols included in the sphere and likelihood values associated to the estimated symbols.
