Abstract
The invention refers to a transmitter that emits data in the form of a group of at least two partial telegrams that together include the data and that are shorter than an individual telegram comprising the data. The transmitter emits the group of partial telegrams according to a hopping pattern that refers to times and/or transmission frequencies of the emission of the individual partial telegrams. Furthermore, the transmitter emits the group of partial telegrams several times and at least twice. Furthermore, the invention relates to a receiver and corresponding methods.
Claims31
A transmitter,
- wherein the transmitter emits data in the form of a group of at least two partial packets that together comprise the data and that are shorter than an individual data packet comprising the data,
- wherein the transmitter emits the group of the partial packets according to a hopping pattern that refers to times and/or transmission frequencies of the emission of the individual partial packets,
- wherein the transmitter emits the group of the partial packets several times and at least twice,
- wherein, for an emission of the group of the partial packets following a preceding emission, the transmitter randomly offsets the hopping pattern used for the preceding emission in time and/or frequency.
A method for emitting data,
- wherein data is emitted in the form of a group of at least two partial packets that together comprise the data and that are shorter than an individual data packet comprising the data,
- wherein the group of the partial packets is emitted according to a hopping pattern that refers to times and/or transmission frequencies of the emission of the individual partial packets, and
- wherein the group of the partial packets is emitted several times,
- wherein, for an emission of the group of the partial packets following a preceding emission, the hopping pattern used for the preceding emission is randomly offset in time and/or frequency.
A receiver,
- wherein the receiver receives from a transmitter partial telegrams that together comprise data and that are shorter than an individual data packet comprising the data, and
- wherein the receiver identifies at least one hopping pattern used by the transmitter when emitting the partial packets, the hopping pattern referring to times and/or transmission frequencies of the emission of the individual partial packets,
- wherein the group of partial packets is emitted by the transmitter multiple times and at least twice,
- wherein, for an emission of the group of the partial packets following a preceding emission, the hopping pattern used for the preceding emission is randomly offset in time and/or frequency.
A method for receiving data,
- wherein partial packets are received that together comprise the data and that are shorter than an individual data packet comprising the data, and
- wherein a hopping pattern used when emitting the partial packets is identified, the hopping pattern referring to times and transmission frequencies in the emission of the individual partial packets,
- wherein the group of partial packets is emitted multiple times and at least twice,
- wherein, for an emission of the group of the partial packets following a preceding emission, the hopping pattern used for the preceding emission is randomly offset in time and/or frequency.
A non-transitory digital storage medium having a computer program stored thereon to perform the method for emitting data,
- wherein data is emitted in the form of a group of at least two partial packets that together comprise the data and that are shorter than an individual data packet comprising the data,
- wherein the group of the partial packets is emitted according to a hopping pattern that refers to times and/or transmission frequencies of the emission of the individual partial packets, and
- wherein the group of the partial packets is emitted several times,
- wherein, for an emission of the group of the partial packets following a preceding emission, the hopping pattern used for the preceding emission is randomly offset in time and/or frequency,
- when said computer program is run by a computer.
A non-transitory digital storage medium having a computer program stored thereon to perform the method for receiving data,
- wherein partial packets are received that together comprise the data and that are shorter than an individual data packet comprising the data, and
- wherein a hopping pattern used when emitting the partial packets is identified, the hopping pattern referring to times and transmission frequencies in the emission of the individual partial packets,
- wherein the group of partial packets is emitted multiple times and at least twice,
- wherein, for an emission of the group of the partial packets following a preceding emission, the hopping pattern used for the preceding emission is randomly offset in time and/or frequency,
- when said computer program is run by a computer.
