Xenotran delivers first IBS Test Terminal (a.k.a. the "Devil Duck"). It’s a benchmark tool for the test and development of communications systems based on Integrated Waveform (IW) and Common Interactive Broadcast (CIB) systems. The purpose of the “Devil Duck” is to acquire, monitor, schedule, and decode IBS traffic reception. It does this using Xenotran’s IW/CIB modem (MIL-STD-188-181C) and Multiple Access layer interface (MIL-STD-188-183B).
Xenotran to develop a Single Channel Telemetry Receiver. The Telemetry Receiver takes Intermediate Frequency (IF) from down converters attached to polar Telemetry or geo-stationary antenna systems. The receiver will handle a wide range of modulation types, symbol rates, and forward error correction schemes. Modulation schemes include PM, BPSK, QPSK, UOQPSK, SQPSK and require symbol rates ranging from 0.08 to 26.25 Mbps.

RF/IF Conversion Board. Xenotran introduces a new test and development tool for CIB/IW waveform design. This RF/IF board is a wideband RF front-end, with full duplex transmit and receive capabilities. This tool supports COTS D/A and A/D development boards to facilitate RF waveform synthesis and receive RF signals in the UHF SATCOM band. The transmitter chain takes a modulated I/Q (Q is optional) input signal at 0 dBm, amplifies and frequency shifts the signal to an output range from 290 MHz to 318 MHz. The input signal range from 7 to 35 MHz is readily producible for a majority of COTS D/A development boards. The receive chain has an input RF bandwidth range from 240 to 268 MHz. The receiver provides about 72 dB of gain, and frequency shifts the incoming signal down to a range from 7 to 35 MHz, where it can be readily sampled by a COTS A/D development board. The RF/IF board provides an extremely low phase noise OCXO reference clock and can take an external 10 MHz reference as test requirements warrant. Furthermore, a cross mix signal is provided that gives the test platform an RF loopback capability for UHF SATCOM RF testing without a satellite simulator.

Xenotran receives large modem development and integration contract from Thales to adopt their Radio Platform AN/PRC-148 JEM to IW. Continuing our involvement with the IBS IW/CIB program, Xenotran won a contract to develop demodulation firmware. Utilizing the IBS IW/CIB software developed under the DISA program, Xenotran will leverage their MIL-STD-188-183B/181C Library. Xenotran will transition the existing COTS Hunt Engineering platform to a new TDB COTS development platform. Xenotran’s POSIX based design allows for easy migration to any targeted platform. Our expertise, especially at the physical 188-181C modem layer continues to expand. At this time, we have implemented CPM and the various modulation schemes in both FPGA and DSP based architectures. The most challenging part of these types of programs involves backward integration of new modulation and waveforms on legacy radios that are often several years old. Our expertise shortens development effort, cost and time.

Xenotran designs, develops and test the MIL-STD 188-183B and MIL-STD 188-182B waveforms.
Adaptive Filter to Mitigate Narrowband and Multi-Path Interference. Xenotran completes SBIR Phase I to design an adaptive filtering system capable of mitigating the effects of narrowband interference and multi-path distortion on a Multi-h Continuous Phase modulation (CPM) modulated channel. The adaptive filtering system will be based on the Least-Mean-Square (LMS) algorithm and will exploit the non-linear behavior of LMS to improve system performance. The system will also capitalize on turbo equalization techniques, iterating between equalizer and soft-input soft-output (SISO) demodulation of the quaternary, Multi-h CPM trellis to further improve system performance. Such an iterative adaptive filtering system is directly applicable to UHF SATCOM receivers, specifically receivers complying with MIL-STD-188-181B/C standards, where narrow band interference and multi-path distortion are of concern.
