Abstract: We present a structure for reduced complexity iterative demodulation and decoding of partial response continuous phase modulation (CPM) when serially concatenated with a convolutional code.

UPSC Electrical Engineering Syllabus: Electrical Engineering is a popular optional subject in the UPSC Mains exam. Aspirants should choose an Electrical engineering subject as optional only if they ...

Abstract: For terrestrial free space optical (FSO) systems, we investigate the use of pulse position modulation (PPM) which has the interesting property of being average-energy efficient. We first ...

We propose and experimentally demonstrate a coherent digital-analog radio-over-fiber (DA-RoF) system and achieve the transmission of Tb/s common public radio interface (CPRI)-equivalent data rate for ...

Metasurface-based terahertz (THz) modulators, which carry information by changing the spatial pattern of the metasurface at every symbol time, are an important component to establish low-cost ...

The goal of this app is to make it trivial to demodulate common RF signals, and provide a digital worksheet for your reverse engineering efforts. You do if you need to capture transmissiosn from your ...

Complex, highly sophisticated communication is fundamental to the human experience — to being human. Play is likewise important to our intellectual, creative, and social development. Today much of our ...

Signal reliability is paramount in many wireless applications. For example, crane controls or other critical control equipment must not lose connection as the equipment moves. Stage actors must ...

The quantum states of two laser pulses—coherent states—are never mutually orthogonal, making perfect discrimination impossible. Even so, coherent states can achieve the ultimate quantum limit for ...
