= Spatial multiplexing
{wiki=Spatial_multiplexing}
Spatial multiplexing is a technique used in multiple-input multiple-output (MIMO) communication systems to enhance data transmission rates and improve spectral efficiency. In spatial multiplexing, multiple spatial streams (data streams) are transmitted simultaneously over the same frequency channel using multiple antennas, both at the transmitter and the receiver. Here are the key aspects of spatial multiplexing: 1. **Multiple Antennas**: The technique relies on having multiple antennas at both the transmitter and receiver ends.
