Raman optical time-domain reflectometry (ROTDR) inherently balances sensing range, spatial resolution, and temperature accuracy through the pulse duration dictated by the OTDR position principle.

The LTE physical layer (PHY) is a highly complex and optimized signal processing chain designed to reliably transmit data over a challenging wireless channel. Its primary function is to transform data ...

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: We propose and experimentally demonstrate a hybrid digital-analog radio-over-fiber technique based on cascaded digital PCS-121-QAM modulation and analog pulse code modulation for each radio ...

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 ...

Transport Block is a packet of data which is passed between the MAC and Physical layers. It is passed downwards at the transmitter and upwards at the receiver. A Transport Block undergoes Physical ...

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 ...
