Кодируем как по проводу: как представить категориальные данные для нейросети

Что общего между нейросетью и радиопередатчиком? В этой статье я рассматриваю кодирование категориальных признаков как процесс передачи информации через сигнальные каналы — с гармониками, фазами, QAM-созвездиями и функциями активации, превращающими данные в управляемые сигналы.

Кодируем как по проводу: как представить категориальные данные для нейросети

Работая над собственным проектом Rainbow.Net — нейросетью прямого обучения — я столкнулся с интересной задачей: нейронное кодирование , при котором предполагается, что сигналы, передаваемые между...

16-APSK Modulator on FPGA using PipelineC HDL

Introduction Amplitude and Phase Shift Keying (APSK) is a modulation technique used in Radio frequency (RF) systems that combine two existing techniques: ASK (Amplitude shift keying) and PSK (Phase shift keying), the first encodes data as amplitude (voltage) changes on the signal, and the second enc

Tecnicamente, il Wi-Fi 7 (ratificato nel 2022) è il nome “semplice” dello standard 802.11be, come Wi-Fi 6 lo è per l’802.11ax, mentre Wi-Fi 5 è lo standard 802.11ac.

Come tutte le precedenti norme Wi-Fi, il Wi-Fi 7 sarà retrocompatibile. I tuoi dispositivi esistenti saranno in grado di connettersi a un trasmettitore Wi-Fi 7 (router o punto di accesso),

Wi-Fi 7, lo standard che cambia i riferimenti del wireless

Il Wi-Fi 7 include degli aggiornamenti talmente importanti che può essere considerato un game changer così come lo è stato l'arrivo del 5G nelle reti mobili.

#random modulation procedure starts with two #stochastic baseband signals, { x_{c}(t)} and { x_{s}(t)}, whose frequency spectrum is non-zero only for {f\in [-B/2,B/2]}. It applies #qam to combine these with a carrier frequency { f_{0}} (with { f_{0}>B/2}) to form signal {x(t)}
