A digital communication project using OFDM and 32-QAM

Tahmid blogged about a digital communication project using OFDM and 32-QAM as their ECE4670 final project: This builds on a previous lab, where orthogonal frequency division multiplexing (OFDM) is used with on/off keying to send data over the channel. This scheme achieved a data rate of about 14,000 bits per second with zero errors, resulting […]

MIT online course: Principles of Digital Communications I

As part of their ongoing OpenCourseWare program, MIT is offering the free online course “Principles of Digital Communication I.” Course description: The course serves as an introduction to the theory and practice behind many of today’s communications systems. Topics covered include: digital communications at the block diagram level, data compression, Lempel-Ziv algorithm, scalar and vector […]

App note: Intro to digital communications systems

Digital modulation techniques are seeing increasing use worldwide. In the US, the FCC is actually mandating narrowband digital mobile radio (DMR) for certain Land Mobile Radio (LMR) users as explained in this Digital Mobile Radio Association white paper. Datasheets for various chips increasingly made reference to acronyms like GMSK, FSK and others. Agilent has published […]
