Assignee: INSTITUT MINES TELECOM
Field: Computer technology (Electrical engineering)
Classification: CPC G  H  Y | IPC G  H

Claim 0:
1. A decoder configured to decode a signal received through a transmission channel represented by a channel matrix using a search sphere radius, the decoder comprising a radius determination device for determining said search sphere radius from a preliminary radius, wherein the radius determination device is configured to:
i. apply a machine learning algorithm to input data derived from said received signal, said channel matrix and a current radius, the current radius being initially set to the preliminary radius, which provides a current predicted number of lattice points associated with said current radius;
ii. compare said current predicted number of lattice points to a given threshold;
iii. update said current radius if said current predicted number of lattice points is strictly higher than said given threshold, said current radius being updated by applying a linear function to said current radius;
steps i to iii being iterated until a termination condition is satisfied, said termination condition being related to the current predicted number, the radius determination device being configured to set the search sphere radius to the current radius in response to the termination condition being satisfied.
