In this paper, we describe the necessary procedures for accurately simulating digital wireless communication systems operating in the mediumband, aimed at both beginners and experts. In the research literature, digital wireless communication systems are typically simulated in the discrete-time complex baseband domain, where pulse shaping, upconversion, mixing, carrier synchronization, and symbol timing synchronization are often ignored. These assumptions are indeed sufficient in most cases, but to capture the essence of communication in the mediumband, certain physical layer (PHY) operations should be simulated in detail. In this paper, we concisely describe how to simulate a mediumband wireless communication scenario from a single transmitter (TX) to a single receiver (RX) in MATLAB, elaborating the operation of key PHY subsystems. The approach described here ensures that the simulated system captures the delicate dynamics of mediumband wireless communication, including the effect of deep fading avoidance.
