Gain early access to lectures and labs for the Applied RF Engineering II - Signals and Propagation course as lectures and labs are published as part of your RF Mentor Academy Subscription! See our subscription blog posting for all the details.
This course is the second installment in our Applied RF Engineering Certification program.
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.
