The inventions relates to a decoding of a multidimensional received signal corresponding to a discrete multidimensional coded signal transmitted through a channel. For reduction of complexity, it comprises the following steps:
- preprocessing (54) applied to a subset of bins within a set of time/frequency bins to build channel equivalent matrices restricted to the subset;
- interpolation (58) for remaining time/frequency bins with respect to the channel equivalent matrices restricted to the subset to build channel equivalent matrices associated with the remaining time/frequency bins ; and
- decoding (55) of an observation with a lattice decoding by using the channel equivalent matrices associated to the set of time/frequency bins.
