Abstract
Detecting a boundary within a transmitted packet is disclosed. A first symbol of the transmitted packet is received in a band. A second symbol of the transmitted packet is received in the band. The first and second symbols are compared. The boundary within the transmitted packet is detected based at least in part on the comparison of the first symbol and the second symbol and the band.
Claims24
A method of detecting a boundary within a transmitted packet including:
- receiving, by an interface, a first symbol of the transmitted packet in a band;
- receiving, by an interface, a second symbol of the transmitted packet in the band, wherein receiving the first symbol and receiving the second symbol correspond to different cycles of a Time Frequency Code (TFC);
- comparing the first symbol and the second symbol;
- and
- detecting the boundary within the transmitted packet based at least in part on the comparison of the first symbol and the second symbol and the band.
A method of detecting a boundary within a transmitted packet including:
- receiving, by an interface, a first symbol of the transmitted packet in a band;
- receiving, by an interface, a second symbol of the transmitted packet in the band, wherein receiving the first symbol and receiving the second symbol correspond to a same position in a Time Frequency Code (TFC);
- comparing the first symbol and the second symbol;
- and
- detecting the boundary within the transmitted packet based at least in part on the comparison of the first symbol and the second symbol and the band.
A method of detecting a boundary within a transmitted packet including:
- receiving, by an interface, a first symbol of the transmitted packet in a band;
- receiving, by an interface, a second symbol of the transmitted packet in the band, wherein between receiving the first symbol and receiving the second symbol a third symbol is received on a different band;
- comparing the first symbol and the second symbol;
- and
- detecting the boundary within the transmitted packet based at least in part on the comparison of the first symbol and the second symbol and the band.
A method of detecting a boundary within a transmitted packet including:
- receiving, by an interface, a first symbol of the transmitted packet in a band;
- receiving, by an interface, a second symbol of the transmitted packet in the band, wherein for the boundary to be detected the band corresponds to a last position in a Time Frequency Code (TFC);
- comparing the first symbol and the second symbol;
- and
- detecting the boundary within the transmitted packet based at least in part on the comparison of the first symbol and the second symbol and the band.
A method of detecting a boundary within a transmitted packet including:
- receiving, by an interface, a first symbol of the transmitted packet in a band;
- receiving, by an interface, a second symbol of the transmitted packet in the band;
- comparing the first symbol and the second symbol, wherein comparing the first symbol and the second symbol includes correlating samples of the first symbol and samples of the second symbol;
- and
- detecting the boundary within the transmitted packet based at least in part on the comparison of the first symbol and the second symbol and the band, wherein a sign derived from the correlated samples is used to detect the boundary within the transmitted packet.
A method of detecting a boundary within a transmitted packet including:
- receiving, by an interface, a first symbol of the transmitted packet in a band;
- receiving, by an interface, a second symbol of the transmitted packet in the band;
- comparing the first symbol and the second symbol;
- and
- detecting the boundary within the transmitted packet based at least in part on the comparison of the first symbol and the second symbol and the band, wherein detecting the boundary within the transmitted packet includes determining a plurality of metrics such that each metric corresponds to a position within a Time Frequency Code (TFC).
A system for detecting a boundary within a transmitted packet including:
- an interface configured to:
- receive a first symbol of the transmitted packet in a band;
- and
- receive a second symbol of the transmitted packet in the band, wherein receiving the first symbol and receiving the second symbol correspond to different cycles of a Time Frequency Code (TFC);
- a comparator configured to compare the first symbol and the second symbol;
- and
- a detector configured to detect the boundary within the transmitted packet based at least in part on the comparison of the first symbol and the second symbol and the band.
