Abstract
Methods and apparatuses are provided for transmitting and receiving a-priori information. The transmitting method includes generating, by circuitry of a transmission apparatus, the a-priori information based on a sampling frequency and a channel bandwidth of a signal to be transmitted. The a-priori information is appended to a data signal by the circuitry. The circuitry transmits the data signal including the appended a-priori information to a reception apparatus.
Claims14
A method for transmitting a-priori information, the method comprising:
- generating, by circuitry of a transmission apparatus, a chirp signal that represents the a-priori information based on a sampling frequency and a channel bandwidth of a signal to be transmitted, the chirp signal including at least one burst with a chirp rate equal to the sampling frequency and with a maximum frequency equal to the channel bandwidth;
- appending, by the circuitry, the chirp signal that represents the a-priori information to a data signal;
- and
- transmitting, by a transmitter, the data signal including the appended chirp signal that represents the a-priori information to a reception apparatus.
A method for receiving a-priori information, the method comprising:
- receiving, by a receiver of a reception apparatus, a transmitted signal, the transmitted signal including a-priori information appended to a data signal;
- detecting, by circuitry of the reception apparatus, a chirp signal that represents the a-priori information included in the transmitted signal, the chirp signal including at least one burst with a chirp rate equal to the sampling frequency and with a maximum frequency equal to the channel bandwidth;
- and
- determining, by the circuitry, a sampling frequency and a channel bandwidth associated with the transmitted signal based on the detected chirp signal that represents the a-priori information.
A transmission apparatus, comprising:
- circuitry configured to:
- generate a chirp signal that represents a-priori information based on a sampling frequency and a channel bandwidth of a data signal to be transmitted, the chirp signal including at least one burst with a chirp rate equal to the sampling frequency and with a maximum frequency equal to the channel bandwidth;
- and
- append the chirp signal that represents the a-priori information to the data signal;
- and
- a transmitter configured to transmit the data signal including the appended chirp signal that represents the a-priori information to a reception apparatus.
A reception apparatus, comprising:
- a receiver configured to receive a transmitted signal, the transmitted signal including a-priori information appended to a data signal;
- and
- circuitry configured to:
- detect a chirp signal that represents the a-priori information included in the transmitted signal, the chirp signal including at least one burst with a chirp rate equal to the sampling frequency and with a maximum frequency equal to the channel bandwidth;
- and
- determine a sampling frequency and a channel bandwidth associated with the transmitted signal based on the detected chirp signal that represents the a-priori information.
