As an ultra-wideband microwave signal, amplitude shift keying (ASK) can be used in many occasions, such as electronic warfares, wireless communications and modern radar systems. Initially, ASK ...

In the recent decade, various schemes of field recovery with direct detection have been investigated in short-reach optical communications. Since direct detection generally provides only intensity ...

The generation of single sideband (SSB) signals first came to my attention via ham radio back in the early 1960s. My call was then and still is WA2IBH. The best phonetic I had for that call sign was ...

This year, we recognize John R. Carson for two major contributions to communications technology: the invention of single-sideband (SSB) modulation and his rule for estimating frequency modulation (FM) ...

In the old days, a shortwave radio was a major desk fixture. These days, you can get truly diminutive radios. However, most of them only have AM capability (that is, no simple way to receive ...
