As more high-speed amplifier applications deal with communication systems, wired or wireless, a brief introduction and overview of orthogonal frequency division multiplex (OFDM) is necessary. With a ...

Over the past year I’ve been writing about potential transmission standards for a nextgeneration broadcast platform (NGBP). The most promising standards are all based on orthogonal frequency division ...

Since the concepts of digital coding metasurface and programmable metasurface were put forward in 2014, the physical world of electromagnetics has been closely connected to the digital world of ...

Having previously discussed aspects of multiplexing in this column, this month we’ll consider the technology in broader terms. In general, multiplexing is the process of transmitting multiple signals ...
