qzmodem is a ZModem protocol implementation for Qt, which does not rely on any library other than Qt and can be used across platforms.The code passed the test on qt6.6, and it should work on other versions of Qt. XYmodem:https://github.com/QQxiaoming/qxymodem

This project demonstrates a design methodology for optimizing high-quality communication between base stations and clients through enhanced signal-to-noise ratio (SNR). It leverages linear phased array antennas to improve beamforming, enabling precise signal targeting and minimizing interference. This focuses on modern wireless communication system
