==METHOD AND DEVICE FOR TRANSMITTING OFDM SIGNAL, AND METHOD AND DEVICE FOR RECEIVING OFDM SIGNAL - A simplified explanation of the abstract==


This abstract first appeared for US patent application 18156801 titled 'METHOD AND DEVICE FOR TRANSMITTING OFDM SIGNAL, AND METHOD AND DEVICE FOR RECEIVING OFDM SIGNAL

==Simplified Explanation==

The patent application describes a method for transmitting an orthogonal frequency division multiplexing (OFDM) signal in a wireless communication system. The method involves generating a frequency-shifted OFDM baseband signal by shifting the frequency of a first signal by a specific difference. This difference is calculated as the carrier frequency minus a specific frequency, which is chosen from a set of frequencies closest to the carrier frequency and corresponding to integer multiples of a specific subcarrier spacing. The frequency-shifted OFDM baseband signal is then up-converted to the carrier frequency using an analog oscillator to generate an OFDM symbol signal, which is then transmitted at the carrier frequency.

* The method involves generating a frequency-shifted OFDM baseband signal.
* The frequency shift is calculated based on the carrier frequency and a specific frequency chosen from a set of frequencies closest to the carrier frequency.
* The specific frequency is selected from frequencies corresponding to integer multiples of a specific subcarrier spacing.
* The frequency-shifted OFDM baseband signal is up-converted to the carrier frequency using an analog oscillator.
* The up-converted signal is transmitted at the carrier frequency.

== Potential Applications ==
* Wireless communication systems
* Mobile networks
* Internet of Things (IoT) devices
* Wi-Fi networks

== Problems Solved ==
* Efficient transmission of OFDM signals in wireless communication systems
* Frequency shifting and up-conversion of baseband signals
