PhaseLocked Systems has been involved in radar system design,
RF circuit design, operating systems design, intercept
receiver design, DSP design for telephony, and more. A brief
list of recent activities includes
-
Analysis and simulation of 3GPP waveforms in nonlinear
interference and distortion. Includes UMTS, LTE, and most
other active standardized waveforms.
-
Design of an equalizer system for nonlinear SATCOM
channels.
-
Part of the architecture team for three OFDM chipsets.
-
Design of a unique micro-cellular telephony system based
on the WiMAX OFDMA standard.
-
Detailed analysis of A/D and D/A requirements for
OFDMA systems in the presence of intermodulation, mixer
spurs, and adjacent-channel interference.
-
Design of an automated test system for an OFDM chipset.
-
Development of high-fidelity audio path circuitry and
proprietary wireless system architecture for remote audio
systems.
-
Development of a flexible object-oriented simulation
platform for rapid prototyping OFDM(A) systems with
support for accurate evaluation of modulation and
estimation techniques.
