About the Webpage Editor

This online webpage editor is a tool you open in your web browser (like Chrome, Firefox, Safari) that lets you write and edit web code — such as HTML, CSS, and JavaScript — and immediately see the result without installing anything.

This Live HTML Editor Simulator is a simple yet powerful online tool that allows users to write, edit, and instantly preview HTML code in real-time. It's designed to create a fast, responsive, and user-friendly experience for better responsiveness across different devices.

So, this simulator can handle full HTML pages, meaning HTML + internal CSS + internal JavaScript.
But it cannot import external files (like loading an external JavaScript or CSS file by URL) unless you manually add the <link> or <script src=""> tag in your code.

OFDM Symbols and Subcarriers Explained

This article explains how OFDM (Orthogonal Frequency Division Multiplexing) symbols and subcarriers work. It covers modulation, mapping symbols to subcarriers, subcarrier frequency spacing, IFFT synthesis, cyclic prefix, and transmission. Step 1: Modulation First, modulate the input bitstream. For example, with 16-QAM , each group of 4 bits maps to one QAM symbol. Suppose we generate a sequence of QAM symbols: s0, s1, s2, s3, s4, s5, …, s63 Step 2: Mapping Symbols to Subcarriers Assume N sub = 8 subcarriers. Each OFDM symbol in the frequency domain contains 8 QAM symbols (one per subcarrier): Mapping (example) OFDM symbol 1 → s0, s1, s2, s3, s4, s5, s6, s7 OFDM symbol 2 → s8, s9, s10, s11, s12, s13, s14, s15 … OFDM sym...

Theoretical BER vs SNR for binary ASK, FSK, and PSK (with MATLAB Code + Simulator)

📘 Overview & Theory 🧮 MATLAB Codes 🧮 Q-function 📚 Further Reading Bit Error Rate (BER) Equations In ASK, noise directly affects the signal amplitude, making it the most vulnerable since the data is carried in amplitude changes. In FSK, data is represented by frequency variations, and because noise typically impacts amplitude more than frequency, FSK is more robust than ASK. In PSK, data is encoded in the signal phase, and BPSK specifically uses 180-degree phase shifts, creating the greatest separation between signal points and therefore achieving the lowest bit error rate (BER) for the same power level. BER formulas for ASK, FSK, and PSK modulation schemes. ASK BER = 0.5 × erfc(0.5 × √SNR) FSK BER = 0.5 × erfc(√(SNR / 2)) PSK BER = 0.5 × erfc(√SNR) ...
