Abstract: We design serial concatenated multi-input multi-output systems based on low-density parity-check (LDPC) codes. We employ a receiver structure combining the demapper/detector and the decoder ...

A black bar code on a green background, illuminated by red scanner light, looks all black. Modulation – The dark color of bars and the light color of spaces must be uniform. There should only be these ...

Neural firing rates are thought to represent values which code information. There are drawbacks with using biophysical events to represent numbers. (1) Rate code (like any sequence) is inherently slow ...

Cochlear implants (CIs) provide important speech cues to deaf patients, but they fail to support the discrimination of temporal sound features with submillisecond precision. Although CIs rapidly and ...

An incoherent scatter radar in southern China will probe low-latitude ionospheric properties while also sensing meteors and space debris, explain the SYISR leadership team. With the main purpose of ...

Recent single-cell studies have revealed that yeast stress response involves transcription factors that are activated in pulses. However, it remains unclear whether and how these dynamic transcription ...

Inverter circuits are often needed where it is not possible to get AC supply from the grid. An inverter circuit is used to convert DC power to AC power and it can be divided into two types that is ...

Action potentials (APs) are generally produced in response to complex summation of excitatory and inhibitory synaptic inputs. While it is usually considered as a digital event, both the amplitude and ...

Smartphones have long since surpassed the old MP3 player when it comes to portable music, and continue to include more and more impressive audio hardware to win over the audiophile crowd – from front ...

Communication between neurons via synapses is essential for information processing and cognitive function in our brains and is found impaired in many neuropsychiatric disorders. Synaptic transmission ...
