Permutation codes are mathematical constructs that utilise the properties of permutations to encode and protect information, with applications spanning powerline communications, flash memory storage ...

The key parameters of the FSS technique and their impact on EMI performance. How to evaluate FSS performance using simulation, ICs, and a signal generator. Frequency spread spectrum (FSS) is a ...

Despite the obvious difference between a chihuahua and a doberman, the human brain effortlessly categorises them both as dogs, a feat that is thus far beyond the abilities of artificial intelligence.

The proposed CORDIC-less digital polar transmitter demonstrates superior power added efficiency (PAE) and system efficiency (SE) for similar modulation signals. It also supports wider bandwidths, ...

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 ...
