modem-core

Digital modulation and demodulation in pure Rust.

Features

• ASK — Amplitude Shift Keying with envelope detection
• FSK — Frequency Shift Keying with coherent detection
• PSK — Phase Shift Keying (BPSK, QPSK, M-PSK) with constellation analysis
• QAM — Quadrature Amplitude Modulation (4/16/64/256-QAM)
• BER — Bit Error Rate computation and theoretical curves

Modules

Module	Description
ask	ASK modulation and demodulation
fsk	FSK modulation and demodulation
psk	PSK modulation, demodulation, constellation
qam	QAM modulation and demodulation
ber	BER computation and theoretical curves

Quick Start

use modem_core::{psk_modulate, psk_demodulate, ber_compute};

let symbols = [0, 1, 0, 1, 1, 0];
let signal = psk_modulate(&symbols, 2, 100); // BPSK
let demod = psk_demodulate(&signal, 2, 100);

let ber = ber_theoretical_bpsk(10.0); // BER at 10 dB SNR
