Embodiment Construction

[0036] figure 1is a block diagram of an example end-to-end communication system implemented as a neural network, generally indicated by reference numeral 1, in which example embodiments may be implemented. System 1 includes transmitter 2 , channel 4 and receiver 6 . Viewed at the system level, system 1 converts input symbol(s) (also called messages) received at the input to transmitter 2 into output symbols at the output of receiver 6

[0037] Transmitter 2 implements the transmitter algorithm. Similarly, receiver 6 implements a receiver algorithm. As described in detail below, the algorithms of the transmitter 2 and receiver 6 are trained in order to optimize the performance of the system 1 as a whole.

[0038] System 1 thus provides an autoencoder implementing an end-to-end communication system. Autoencoders can be trained with respect to any loss function related to some performance metric, such as Block Error Rate (BLER). (The terms "autoencoder" and "communication ...

Abstract

An apparatus, method and computer program is described comprising: initialising parameters of a transmission system, wherein the transmission system comprises a transmitter, a channel and a receiver, wherein the transmitter includes a transmitter algorithm having at least some trainable weights and the receiver includes a receiver algorithm having at least some trainable weights; updating trainable parameters of the transmission system based on a loss function, wherein the trainable parameters include the trainable weights of the transmitter and the trainable weights ofthe receiver and wherein the loss function includes a penalty term; quantizing said trainable parameters, such that said weights can only take values within a codebook having a finite number of entries that is a subset of the possible values available during updating; and repeating the updating and quantizing until a first condition is reached.

Description

technical field [0001] This specification relates to learning in communication systems. Background technique [0002] A simple communication system consists of a transmitter, a transmission channel, and a receiver. The design of such a communication system may involve the individual design and optimization of each part of the system. An alternative approach is to consider the entire communication system as a single system and seek to optimize the entire system. Although some attempts have been made in the prior art, there are still opportunities for further development in this field. Contents of the invention [0003] In a first aspect, the present specification provides an apparatus comprising: means (such as an initialization or control module) for initializing parameters of a transmission system, wherein the transmission system comprises a transmitter, a channel and a receiver, wherein the transmitter comprises A transmitter algorithm with at least some trainable wei...
