In such situations, advanced ABF techniques, such as the Extended Sample Matrix Inversion Technique (ESMI), are required in order to maximize the interference rejection over the processing interval.
Its direct conversion architecture allows digital filtering for desirable interference rejection and fewer spurious responses.
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.
Features of the FreeWave system include spread spectrum frequency hopping for secure use and interference rejection; 57.6 Kbaud throughput at up to 20 mile range when used with the SoMat 2100 or 2500 field computer systems; programmability through any terminal; operation in point-to-point (currently supported by WinTCS), or point-to-multipoint mode; programmable store and forward repeater which extends the range and allows two repeaters to be used in a link; factory-set serial number for data security; and on-board qualitative and quantitative RF diagnostics for easy field troubleshooting and optimization.
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.
Ruckus Smart Wi-Fi technology brings essential interference rejection capabilities to the strand-mount application, delivering unrivaled performance in the unlicensed bands.
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.
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 to maximize the effectiveness of interference rejection. This requires the storage of data samples while ABF-weight calculation is undertaken, introducing data latency into the system.
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.
