Introduction to Orthogonal Frequency Division Multiplexing
Explore how Orthogonal Frequency Division Multiplexing (OFDM) is applied in wireless communications to efficiently modulate, equalize, and demodulate digital signals. Understand why OFDM is widely used in technologies like WiFi and 4G/5G networks. This lesson guides you through building a simplified OFDM modem, reinforcing key digital signal processing concepts in a practical context.

What we have learned so far can now be applied to build an orthogonal frequency division multiplexing (OFDM) modem.
Background
The OFDM is one of the most popular digital transmission schemes employed in many of the wireless technologies we use every day. Some examples of the wireless networks that use OFDM include:
- Wireless local area networks (LAN)
- WiFi (e.g., IEEE 802.11a,
