Abstract
Various aspects generally relate to communication. In some aspects, a receiver may receive, from a transmitter over a wired infrastructure, a frequency division multiplexed (FDM) signal. The receiver may map the FDM signal to a spatial division multiplexed (SDM) signal including multiple spatial layers, wherein the SDM signal mapped to the FDM signal compensates for a frequency error between the transmitter and the receiver. The receiver may provide the SDM signal to a multiple-input multiple-output (MIMO) transceiver. Numerous other aspects are described.

An apparatus for communication at a receiver, comprising:
- one or more memories;
- and
- one or more processors, coupled to the one or more memories, configured to cause the receiver to:
- receive, from a transmitter over a wired infrastructure, a frequency division multiplexed (FDM) signal;
- map, by a frequency translation component, the FDM signal to a spatial division multiplexed (SDM) signal that includes multiple spatial layers, wherein the SDM signal mapped to the FDM signal compensates for a frequency error between the transmitter and the receiver;
- and
- provide the SDM signal to a multiple-input multiple-output (MIMO) transceiver.
An apparatus for communication at a transmitter, comprising:
- one or more memories;
- and
- one or more processors, coupled to the one or more memories, configured to cause the transmitter to:
- provide, by a multiple-input multiple-output (MIMO) transceiver, a spatial division multiplexed (SDM) signal that includes multiple spatial layers to a frequency translation component;
- map, by the frequency translation component, the SDM signal to a frequency division multiplexed (FDM) signal;
- and
- transmit, to a receiver over a wired infrastructure, the FDM signal, wherein the FDM signal transmitted over the wired infrastructure compensates for a frequency error between the transmitter and the receiver.
