ABSTRACT:
Aspects of a method and system for an optional closed loop mechanism with adaptive modulations for a multiple input multiple output (MIMO) WLAN system are provided. One aspect of the system may utilize properties of Eigenvalue analysis of MIMO systems to reduce the number of bits of binary information required to select a modulation type among a plurality of modulation types for each spatial stream among a plurality of spatial streams. This provides a reduction in the required number of bits when compared to other approaches and accordingly, enable greater flexibility in systems that utilize closed loop feedback mechanisms.
