Abstract
In some implementations, a device may one or more processors. The one or more processors may be configured to perform soft demapping using sphere decoding in multiple input multiple output (MIMO) systems and using different modulation sizes in unequal quadrature amplitude modulation (QAM) across a plurality of spatial streams.
