An antenna array being attachable to a surface is provided. Said antenna array comprises at least two antennas, and a magnetic material and/or an alloy with ferro-magnetic properties for magnetically attaching at least one further antenna.

Antenna array, antenna system and antenna kit, each being attachable to a surface

The present disclosure relates to a radio frequency (RF) measurement system and a method for recording baseband and positioning data. The RF measurement system includes at least one RF measurement device. The RF measurement device includes at least one RF chain and at least one data processing circuit connected to a memory device. The RF measurement device is configured to receive a global navigation satellite system (GNSS) signal. The GNSS signal is indicative of a position and/or a bearing. The RF measurement device is configured to receive at least one analog RF signal different of the GNSS signal. The RF measurement device is configured to convert the at least one analog RF signal into at least one baseband signal. The at least one data processing circuit is configured to store baseband data associated with the baseband signal and positioning data associated with the GNSS signal within the memory device.

Radio frequency measurement system and a method for recording baseband and positioning data

The present disclosure relates to a method of estimating a transmission direction of a transmitter. The method comprises: performing a first measurement by means of a measurement system, thereby obtaining a first measurement value of a first transmitter; performing a second measurement by means of the measurement system, thereby obtaining a second measurement value of a second transmitter; obtaining position information of the first transmitter and the second transmitter; determining a position of the measurement system; and taking the first measurement value, the second measurement value, the position information as well as the position of the measurement system into account in order to estimate the transmission direction of the first transmitter. In addition, a system for estimating a transmission direction of a transmitter is described.

Method and system for estimating a transmission direction of a transmitter

An H-ARQ system wherein the transmission of two consecutive, or sequential, blocks of information bits are considered jointly; i.e., one of the blocks of information being embedded within the other one of the blocks of information. If a retransmission for the first block is necessary, the system processes both blocks jointly. The system is provided with cross-packet coding which extends current H-ARQ schemes for point-to-point communications wherein the transmission of two consecutive block of information bits is considered jointly. If a retransmission for the first block is necessary, the system processes both blocks jointly. This allows both blocks to be decoded without errors at the receiver after the retransmission.
