We all love our wireless devices. We want more features, higher data rates, and improved range. These demands, in turn, require advanced digital protocols. Meanwhile, the number of signal sources is ...

Diverse well describes the myriad digital modulation schemes used in modern voice and data communications. The alphabet soup of terminology extends well beyond the familiar QAM and GMSK fundamentals ...

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 ...

Ever increasing data-transmission speeds coupled with the need to contend with higher-order modulation schemes are presenting optical-communications test-and-measurement challenges. Products ranging ...

Intel Corp. today debuted a new and significantly faster version of its Thunderbolt technology, which is used to connect personal computers with external devices such as displays. Thunderbolt was ...

Opinion: AI-enabled satellite networks are reshaping networking and space systems by turning signals into intelligence for ...

The CP-OFDM modulation scheme will have many options. Variable subcarrier spacing (SCS) will be 3.75, 15, 30, 60, 120, 240, 480 kHz with sub-1 GHz of 15 and 30 kHz and sub-6 GHz of 15, 30, and 60 kHz, ...

Modulation is a technique in which message signal is transmitted to the receiver with the help of carrier signal. Here in modulation, we combine both carrier signal and message signal. In this post, ...

Amateur radio license exams typically have a question about the bandwidths taken up by various modulation types. The concept behind the question is pretty obvious — as guardians of the spectrum, ...
