Summary

TRAINING HOURS: This course is equivalent to 24 hours of classroom training.

The process of coding information onto an RF carrier is a key aspect that enables modern wireless transmission. An RF/wireless engineer needs to understand how information can be represented as changes to the properties of a carrier, as well as the impediments that the carrier faces going from the transmit antenna to the receive antenna. Although the topic is complex, many key concepts are remarkably simple to understand and help to demystify assumptions concerning frequency, range, and bandwidth requirements for example. Furthermore, understanding the basic modulation types serves as a foundation for understanding how today's elaborate commercial standards work, by seeing them as the combination of familiar building blocks alongside other more advanced techniques.

Lab exercises in the course using Octave/Matlab allow the student to explore relationships between time and frequency domains, as well as providing some bonus familiarity and competence with basic DSP algorithms. Some basic modulation signals are explored, and the basic principles of OFDM signal generation are demonstrated.

This is a self-paced course with each student given approximately 5 months to complete the program. During that time, the student has on-demand access to the course materials at a time that is most convenient for their schedule. The course utilizes a Learning Management System, which allows students to log in and access online course material at any time, ask questions and keep track of their progress.

This course is intended for registered students only. Please contact us for group rates at info@besserassociates.com or 650-949-3300. Recording, copying, or re-transmission of classroom material is prohibited.

Alternative On-Demand schedule dates are available. Please contact us at info@besserassociates.com for details.

Learning objectives

Upon completing the course you will be able to:

work with DSP tools to create basic waveforms
view relationships between time and frequency domains
interpret the basic relationship between frequency and path loss
identify basic antenna performance metrics
evaluate wireless standards based on common signal building blocks

Target Audience

This course is intended for students with an engineering background or equivalent practical experience. The material covered is similar to the RF Technology Certification part II. This course includes "lab" sessions using Octave/Matlab examples to create basic signal types and explore their properties in the time and frequency domains. Octave is an open source program that is freely available for download on multiple computer platforms.
