Maximal Ratio Combining (MRC)

Receive technique that combines signals from multiple antennas to improve SNR.

Definition

MRC aligns and weights signals from all receive chains and combines them. The result is a stronger, more reliable signal, especially for single-stream transmissions from legacy clients. It is a receive-side MIMO technique.

Exam tip

MRC helps uplink from weak clients; it is on the receiver side.
