GUARD INTERVAL IN DELAY-DOPPLER DOMAIN - A simplified explanation of the abstract
This abstract first appeared for US patent application 17819464 titled 'GUARD INTERVAL IN DELAY-DOPPLER DOMAIN
Simplified Explanation
- Explanation:**
The patent application describes a method for using a guard interval in a delay-Doppler domain for wireless communication. This involves converting information from the delay-Doppler domain to a time-frequency domain, mapping it to resources in an OFDM resource grid, generating a time-domain waveform with guard intervals, and transmitting it to a node.
- Potential Applications:**
- Wireless communication systems - Radar systems - Satellite communication systems
- Problems Solved:**
- Efficient use of guard intervals in wireless communication - Improved signal processing in delay-Doppler domain - Enhanced communication reliability and performance
- Benefits:**
- Better utilization of resources in OFDM systems - Increased reliability and robustness in wireless communication - Improved signal processing techniques for delay-Doppler domain
Original Abstract Submitted
Certain aspects of the present disclosure provide techniques for using a guard interval in a delay-Doppler domain. A method of wireless communication includes converting information in a delay-Doppler domain to a time-frequency domain, wherein the information includes data and at least one guard interval (GI); mapping the converted information to time and frequency resources of an orthogonal frequency domain multiplexing (OFDM) resource grid in the time-frequency domain; generating a time-domain waveform based on the OFDM resource grid, wherein the time-domain waveform includes one or more GIs; and outputting the time-domain waveform for transmission to a node.
