PID implementation for MIMO system with strong crosstalk
The setup:
Rectangular platform with two sensors providing pitch and roll angles. Four articulated legs at the corners with actuators controlled by the software. Actuator position feedback is also available.
Using manual actuator control the…

Converting beam index to angular units
Assume I have a MIMO channel matrix \$H\$ of dimension [\$N_r\$ \$N_t\$ \$N_f\$] where \$N_r\$ are the number of antennas at the receiver, \$N_t\$ the number of antennas at the transmitter, and \$N_f\$ the number of subbands. If I just look at one…

Identify this component: BEF1592 2143
This component is placed in the signal path next to a multi-band GSM antenna. It seems to have 3 terminals - 1x GND and 2x in signal path. I suspect it is some sort of bandpass filter, but can't locate the exact details anywhere.
[Edit] also added…

Dual band Wi-Fi antenna simultaneous 2.4+5GHz transmission
There are APs that have dual band antennas and seem to offer simultaneous 2.4+5 GHz operation. I wonder how this simultaneous dual band operation technically works (2 radios using one antenna.) A sample AP may have 2x2 MIMO with two antennas…

2T2R with two antennas
Regarding the 2T2R, the device should have two transmitter antennas and two receiver antennas in order to double the data rate. However, as I see different devices, the 2T2R has only two antennas, and 4T4R has four antennas. As I know, most of these…
