PhaseLocked Systems Services

  • Mathematical modeling and simulation

    "If you can't analyze it, don't build it", Maier & Rechtin, The Art of System Architecture

    Dr. Short has been modeling systems for over 30 years and is expert with mathematics and fluent in a number of computer languages including MATLAB and C++. PhaseLocked Systems has developed a variety of models and simulation frameworks allowing us to quickly and efficiently examine a variety of complex questions.

    We are able to model digital modems as well as analog effects including intermodulation and data conversion (A/D and D/A). Our recent efforts include modeling OFDM(A) and spread spectrum modems and we currently have a SATCOM project in which we will enable the customer to operate high-power amplifiers at or near saturation.


  • Architecture Design and Review

    We are well-versed in the practice and theory of system architecture. We have practiced top-down system specification for decades, and are able to use many techniques and tools including object-oriented design using UML and SDL.


  • Requirements Analysis and System Specification

    "If you don't ask for what you want, you are unlikely to get it", Gause and Weinberg, Exploring Requirements

    We are expert in the both the requirements process and the development of specifications. We are thorough and document all results carefully.


  • Validation and Testing

    "Regardless of what has gone before, the acceptance criteria determine what is actually built", Maier & Rechtin

    The end-game of the system development process is critical, and is often ignored until very late in the program. We have assisted clients in designing test suites early in the program.


  • Program planning and project management

    Part of system design is to adequately plan the program. Good program planning is architecture and validation based, and we are solidly grounded in program planning techniques.


  • Patent Support and Review

    We have a great deal of experience in the patent process from patent preparation to assisting in patent litigation. While we are not patent agents or attorneys, we are able to help with the technical side of IP portfolio management.


  • Implementation and Verification
    Through our network of associates, we are able to help with all phases of the system design and implementation.
