4G chipmaker Sequans Communications (NYSE:SQNS) announced on Tuesday that it has added new technology to its LTE chip platforms called Sequans AIR - Active Interference Rejection
In the ABF case, the adaptive weights, which define the phase and gain of each array element, need to be applied to the data from which they were calculated in order to maximize the effectiveness of interference rejection
Using field-proven proprietary FHSS technology, 1x1s provide interference rejection
, enable co-located system operation, increase output power, and maintain data integrity.
Superconducting filter technology offers the capability to simultaneously provide enhanced sensitivity and strong interference rejection
that has the potential to be particularly valuable in the complex radio frequency environment found aboard military aircraft.
G2 has a greatly enhanced interference rejection
system, improved range, improved rejection of standard line locator frequencies and is built with the latest methods to ensure highest quality.
The GNSS RF front-end, based on established market leading front-end technology developed by Septentrio, is characterized by a superb out-of-band interference rejection
to avoid notably device self-interference with other radiation sources such as Bluetooth and WLAN radios, as well as other ambient intentional and non-intentional interference.
In addition, the SF-3050 and Sapphire provide high performance in GNSS receiver sensitivity and signal tracking, as well as multi-path mitigation, interference rejection
and anti-jamming capabilities, while supporting a range of high-speed I/O, including Ethernet, Bluetooth and USB capability.
With narrow RF channel bandwidths providing high interference rejection
, at SAW module prices, the X2010/11 series is suitable for next generation applications.
The pseudorandom noise pattern used in the chipping process repeats itself every symbol, which is somewhat limiting with regard to both the resulting interference rejection
and security properties.
Since multiple mechanisms and sources of interference exist, it must be emphasized that a combination of interference rejection
measures is required to combat the interference.
These filters can provide low distortion filtering, but not close-in interference rejection
