• Spatial multiplexing

Ans. Spatial multiplexing is a technique to utilize the transmitter through antenna by transmitting different channel with separate spacing in MIMO wireless communication.

2. (2 points) Explain how OFDM avoids the problem caused by multipath distortion.

Ans. Multipath distortion problem arise when signal reflected or refracted because of the obstacle on its way so it creates multiple paths and it delays the connection. OFDM systems have maximized spectral efficiency without causing any channel interference so it avoids multipath distortion.
