Digital communication systems involve the transmission of digital information from a source to a destination through a communication channel. The process involves several stages, including:
: Includes simulations for AM and FM systems.
Maximizes the signal-to-noise ratio (SNR) at the receiver. Digital Communication Systems Using Matlab And Simulink

The physical medium. This can be a copper wire, a fiber-optic cable, or free space (wireless). Channels introduce impairments like attenuation, noise, distortion, and interference. For hardware-focused design
Algorithmic designs are stress-tested against real hardware impairments like DC offset, IQ imbalance, and clock synchronization drift.

Analyze signals in time, frequency, and constellation domains.
For hardware-focused design, Simulink provides examples of implementing HDL-optimized OFDM transmitters that can be deployed on FPGAs.
