JOINT FMCW SENSING AND OFDM COMMUNICATIONS - A simplified explanation of the abstract

This abstract first appeared for US patent application 20240183935 titled 'JOINT FMCW SENSING AND OFDM COMMUNICATIONS

Simplified Explanation

The abstract describes a wireless device that can transmit and/or receive both FMCW and OFDM signals using the same time and frequency resources. The device separates the FMCW waveform from the OFDM waveform by a buffer zone with a gap in frequency to reduce interference.

• The wireless device can transmit and receive FMCW and OFDM signals simultaneously.
• The FMCW waveform is separated from the OFDM waveform by a buffer zone with a gap in frequency to minimize interference.

Potential Applications

This technology could be applied in radar systems, communication devices, and IoT devices that require simultaneous transmission and reception of different types of signals.

Problems Solved

1. Interference between FMCW and OFDM signals. 2. Efficient use of time and frequency resources for simultaneous transmission and reception.

Benefits

1. Improved signal quality. 2. Enhanced spectrum efficiency. 3. Increased data throughput.

Potential Commercial Applications

Optimized spectrum sharing in wireless communication systems.

Possible Prior Art

Prior art may include techniques for frequency separation of different types of signals in wireless communication systems.

Unanswered Questions

How does the device handle dynamic changes in the interference level between FMCW and OFDM waveforms?

The abstract does not provide details on how the device adapts to varying interference levels between the FMCW and OFDM signals.

What impact does the buffer zone with a gap in frequency have on the overall data transmission rate of the device?

The abstract does not address how the buffer zone affects the data transmission rate of the wireless device.

Original Abstract Submitted

aspects presented herein may enable a wireless device (e.g., a joint fmcw radar and communication system) to transmit and/or receive an fmcw signal and an ofdm signal using the same time and frequency resources. in one aspect, a first wireless device receives an indication of a scheduled transmission for an fmcw waveform via a set of time-frequency resources. the first wireless device transmits or receives the fmcw waveform via the set of time-frequency resources based on the indication, where the fmcw waveform is separated from an ofdm waveform by a buffer zone including a first gap in frequency, where the first gap in frequency is based on an interference level between the fmcw waveform and the ofdm waveform.
