Patent ID: 11894960
Assignee: NOKIA TECHNOLOGIES OY
Field: Digital communication (Electrical engineering)
Classification: CPC H  G | IPC G  H

Claim 0:
1. An apparatus, comprising:
at least one processor, and
at least one memory including a computer program code, wherein the at least one memory and the computer program code are configured, with the at least one processor, to cause the apparatus to:
receive a modulated radio signal transmitting coded information bits;
perform demodulating on the modulated radio signal, wherein demodulating comprises performing orthogonal time frequency space demodulation;
perform equalization on the demodulated radio signal to obtain equalized symbols;
obtain log-likelihood ratios for the coded information bits from the equalized symbols using a trained machine learning model;
reconstruct the coded information bits; and
wherein the machine learning model is trained jointly with transmitter windowing optimizing and receiver windowing optimizing, wherein the transmitter window optimizing and receiver window optimizing comprises optimizing transmitter windowing parameter and receiver windowing parameter.
