Abstract
In implementations of signal processing for OFDM radar systems, an OFDM transceiver of an ISAC system is operated in full-duplex mode in a downlink communication phase. The ISAC system generates sensing symbols for an OFDM radar system by combining OFDM communication symbols and repetitions of the OFDM communication symbols as the sensing symbols. The OFDM transceiver attenuates subcarriers of received sensing symbols for processing by the OFDM radar system to increase a signal-to-noise ratio of the received sensing symbols.
Claims20
A method comprising:
- operating, by an integrated sensing and communication (ISAC) system, an orthogonal frequency division multiplication (OFDM) transceiver in full-duplex mode in a downlink communication phase;
- and
- generating, by the ISAC system, sensing symbols for an OFDM radar system by combining communication symbols and repetitions of the communication symbols.
An integrated sensing and communication (ISAC) system comprising:
- an orthogonal frequency division multiplication (OFDM) radar system configured to process sensing symbols comprising communication symbols and repetitions of the communication symbols;
- and
- an OFDM transceiver configured to:
- operate in full-duplex mode in a downlink communication phase.
A non-transitory computer-readable medium storing a set of executable instructions, the set of executable instructions to manipulate at least one processor to:
- operate an orthogonal frequency division multiplication (OFDM) transceiver of an integrated sensing and communication (ISAC) system in full-duplex mode in a downlink communication phase;
- generate sensing symbols for an OFDM radar system of the ISAC system by combining communication symbols and repetitions of the communication symbols;
- and
- attenuate subcarriers of received sensing symbols for processing by the OFDM radar system to increase a signal-to-noise ratio of the received sensing symbols.
