Description

Technical Field

[0001] The present invention relates to a receiver, a system comprising such a receiver, and a receiving method. In particular, the present invention relates to a receiver with antenna detection, in particular automatic antenna detection, preferably for receiver optimization, a system comprising such a receiver and at least one antenna, and a corresponding receiving method. Background Art

[0002] In general, with an increasing number of communication applications providing wireless connectivity, there is an increasing demand for receivers, systems comprising such receivers, and reception methods which allow cheap and fast antenna detection, in particular automatic antenna detection, in order to make these applications more efficient, in particular with regard to improved receivers.

[0003] Document US2020 / 0313711 A1 relates to a system comprising a radio frequency (RF) connector terminal configured to be connected to an antenna and an RF transmitter that sends RF power to the RF connector terminal. The system also includes a power measuring unit and a controller, the power measuring unit measuring (as a first power measurement) a first RF power in the RF transmitter power reflected by the RF connector terminal, and the controller causing a discontinuity in the transmission path between the RF transmitter and the RF connector terminal. The power measuring unit also measures (as a second power measurement) a second RF power in the RF transmitter power reflected from the discontinuity. The controller also determines whether the first antenna is connected to the RF connector terminal based on the first power measurement and the second power measurement. Disadvantageously, this antenna detection using antenna return loss requires not only the power measuring unit but also the RF transmitter, making the antenna detection expensive and slow. Summary of the Invention

[0004] It is therefore an object of the present invention to provide a receiver, a system comprising such a receiver, and a reception method which allow antenna detection, in particular automatic antenna detection, thereby ensuring low costs and low time consumption.

[0005] This object is solved by the features of the receiver, the features of a system comprising such a receiver, and the features of the receiving method according to the invention.The invention comprises further developments.

[0006] According to a first aspect of the present invention, a receiver is provided. The receiver comprises: at least one port for directly or indirectly connecting at least one antenna; and a processing unit connected to the at least one port. In this case, the processing unit is configured to measure at least one noise parameter with respect to the at least one antenna, in particular to measure the at least one noise parameter within a specific frequency range. In addition, the processing unit is configured to associate the at least one noise parameter measured accordingly with at least one antenna load characteristic for detecting the at least one antenna and / or for determining the corresponding type of the at least one antenna. Advantageously, not only low costs but also low time consumption can be ensured.

[0007] It is noted that it may be particularly advantageous if the processing unit is configured to measure the at least one noise parameter with respect to the at least one antenna when the at least one antenna is isolated, in particular to measure the at least one noise parameter within a specific frequency range.

[0008] It should also be noted that the processing unit does not necessarily have to be arranged inside the housing of the receiver. For example, the processing unit can be a processing device, in particular a processing device outside the housing of the receiver, such as a personal computer, laptop, smartphone, tablet computer, etc.

[0009] With regard to the case where the at least one antenna is indirectly connected to the at least one port, it is noted that in this case the at least one antenna may be connected to the at least one port via an element, preferably via an active or passive element, more preferably via a signal modifying element, most preferably via a downconverter or an upconverter.

[0010] According to one implementation of the first aspect of the present invention, the receiver further comprises a storage unit connected to the processing unit. In this case, the storage unit is configured to store the at least one antenna loading characteristic. Advantageously, for example, the storage unit may include a table comprising the at least one noise parameter (e.g., noise figure) versus frequency.

[0011] In addition or as an alternative to using the storage unit, it is noted that it may be particularly advantageous if the processing unit comprises a storage capability configured to store the at least one antenna loading characteristic or the table.

[0012] According to another implementation of the first aspect of the present invention, the at least one antenna loading characteristic includes or is at least one predefined antenna loading characteristic, in particular, at least one antenna loading characteristic predefined in the receiver. Additionally or alternatively, the at least one antenna loading characteristic includes or is at least one characteristic for a matched load, in particular a 50 ohm matched load, and / or an open load and / or a short circuit. Advantageously, for example, the storage unit or the storage capacity of the processing unit may each include at least one table of corresponding antenna types and the at least one antenna loading characteristic.

[0013] According to another implementation form of the first aspect of the present invention, the at least one noise parameter includes or is at least one noise pattern, in particular at least one noise coefficient.

In this case, the adjustment unit is configured to adjust the gain and / or dynamic range of the receiver based on the corresponding detection of the at least one antenna and / or the corresponding determination of the type of the at least one antenna. Advantageously, for example, the adjustment unit can access a table or lookup table, which in particular includes at least one corresponding antenna type and the at least one antenna loading characteristic, preferably stored by the storage unit or the storage capacity of the processing unit, in particular for adjusting and / or calibrating the receiver.

[0015] Further advantageously, in particular in the case of adjusting the gain and / or dynamic range of the receiver, the adjustment unit and / or the processing unit can be configured to perform post-processing, in particular with regard to receiver optimization, preferably based on the table or look-up table, or based on the corresponding antenna type selected from the table or look-up table.

Advantageously, for example, when a user replaces an antenna in use with another antenna, the receiver allows corresponding optimization with respect to the other antenna, in particular without additional input from the user, thereby saving time.

[0017] According to another implementation form of the first aspect of the present invention, in particular in the case where the at least one antenna changes or is changed, the processing unit is configured to receive and / or process at least one change signal to trigger an update of the at least one noise parameter measured accordingly and / or an update of the association of the at least one noise parameter measured accordingly with the at least one antenna load characteristic. Advantageously, for example, the change signal can be an interrupt signal, thereby allowing polling routines to be avoided, which results in increased efficiency.

[0018] According to another implementation form of the first aspect of the present invention, the receiver further comprises a communication unit connected to the processing unit. In this case, the communication unit is configured to provide a data connection, in particular a data connection for controlling the receiver.

[0022] According to another implementation of the first aspect of the present invention, the processing unit is configured to detect a change in the at least one noise parameter at a time point, in particular at a time point in the absence of a significant trigger signal. Advantageously, the change can be a sudden change, for example, thereby improving the reliability of receiver optimization.

[0023] According to another implementation form of the first aspect of the present invention, the processing unit is configured to measure the at least one noise parameter when the at least one antenna does not receive a specific frequency or power at at least one specific frequency. Advantageously, for example, in particular when measuring the at least one noise parameter, the processing unit can be configured to utilize time gaps and / or frequency gaps with respect to any signal received by the at least one antenna.

[0024] For the sake of completeness, it should be noted that, in particular when measuring the at least one noise parameter, the at least one antenna can be shielded, for example, by means of a Faraday cage or a metal cage. It can be particularly advantageous if the processing unit is configured to enable such shielding. For example, the processing unit can be connected to an actuator for opening or closing the Faraday cage or metal cage arranged accordingly with respect to the at least one antenna.

[0025] According to another implementation form of the first aspect of the present invention, the processing unit is configured to interpret the at least one antenna having no received power as receiving noise only at the specific frequency or at least one specific frequency. Advantageously, for example, at least one noise figure can be determined efficiently and reliably.

The system comprises a receiver according to the first aspect of the present invention or any implementation thereof, and at least one antenna directly or indirectly connected to the receiver, in particular to at least one port of the receiver.
