Problems solved by technology

[0006] However, efficient and accurate ANNs are still complex and thus require a lot of computing resources (CPU, GPU or dedicated hardware), which is a big disadvantage in the case of wireless communication

Embodiment Construction

[0079] refer to figure 1 , shows the transmitter 1.1 sending a radio signal to the receiver 1.2. The receiver 1.2 is within the cell coverage of the transmitter 1.1. The transmission may be OFDM based transmission. In this example, the receiver 1.2 is a mobile terminal and the transmitter 1.1 is a fixed station, which in the context of LTE is a base station. The transmitter 1.1 may also be a mobile terminal and the receiver 1.2 may be a fixed station. Both the transmitter 1.1 and the receiver 1.2 may be mobile terminals.

[0080] The transmitter 1.1 comprises a communication module (COM_trans) 1.3, a processing module (PROC_trans) 1.4 and a memory unit (MEMO_trans) 1.5. MEMO_trans 1.5 includes a non-volatile unit to retrieve the computer program, and a volatile unit to retrieve the parameters of the transmitter scheme (modulation scheme applied, etc.). PROC_trans1.4 is configured to process the data to be transmitted according to the transmitter scheme including encoder ...

Abstract

The invention relates to a method for decoding at least M0 symbols X0 1,..., X0 M0 received from a transmitter through a wireless communication medium, said received symbols representing symbols encoded by an encoder E of the transmitter, said method comprising: inputting in a decoder the M0 symbols X0 1,..., X0 M0, said decoder comprising an artificial neural network system, wherein at least an activation function of the artificial neural network system is a multiple level activation function.

Description

technical field [0001] The present invention relates to decoding data in a wireless communication system. Background technique [0002] The invention relates more precisely to an artificial neural network for decoding received radio signals. [0003] Traditionally, in wireless communication systems, transmitters and receivers implement specific schemes through multiple components to be able to process the radio signals that send data. [0004] exist figure 2 In , an example of a scheme of a transmitter (referred to as a transmitter scheme) and a corresponding scheme of a receiver (referred to as a receiver scheme) in a wireless communication system is shown. Encoding / decoding of radio signals in such systems (transmitter and receiver) is critical and must be traded off between transmission rate, transmission robustness leading to decoding errors, and receiver complexity. [0005] Recently, however, artificial neural networks (ANNs) have been used to replace components of ...
