Abstract
Embodiments of a device for wireless communication are disclosed. In some embodiments, the device includes: a transceiver configured to receive a message from a second device and at least one processor. The processor is communicatively coupled to the transceiver and is configured to: generate a response message includes a SYNC portion, a start frame delimiter (SFD) portion, and a cipher portion. The SYNC portion includes a sequence of symbols forming a preamble. The cipher portion includes a ciphered sequence of pseudo-randomized pulses. The transceiver is further configured to transmit the response message.
Claims18
A device for wireless communication, the device comprising:
- a transceiver configured to:
- receive a message from a second device;
- at least one processor communicatively coupled to the transceiver, the at least one processor configured to:
- generate a response message comprising a SYNC portion, a start frame delimiter (SFD) portion, and a cipher portion, wherein:
- the SYNC portion comprises a sequence of symbols forming a preamble;
- and
- the cipher portion comprises a ciphered sequence of pseudo-randomized pulses;
- the transceiver further configured to:
- transmit the response message.
A method comprising:
- receiving a message at a transceiver from a second device;
- generating a response message comprising a SYNC portion, a start frame delimiter (SFD) portion, and a cipher portion, wherein:
- the SYNC portion comprises a sequence of symbols forming a preamble;
- and
- the cipher portion comprises a ciphered sequence of pseudo-randomized pulses;
- transmitting the response message.
A non-transitory computer readable medium that stores computer executable instructions, wherein, in response to executing the computer executable instructions, a processor is configured to:
- receive a message at a transceiver from a second device;
- generate a response message comprising a SYNC portion, a start frame delimiter (SFD) portion, and a cipher portion, wherein:
- the SYNC portion comprises a sequence of symbols forming a preamble;
- and
- the cipher portion comprises a ciphered sequence of pseudo-randomized pulses;
- transmitting the response message.
