Abstract

The subject matter disclosed herein provides methods and apparatus for determining a singular value decomposition. In one aspect, there is provided a method. The method may include receiving a plurality of signals transmitted by a base station implementing a plurality of antennas configured for a multiple-input and multiple-output transmission. Moreover, one or more singular vectors may be determined using a closed form singular value decomposition. The one or more determined singular vectors may be provided to a precoder at the base station as feedback. Related systems, apparatus, methods, and/or articles are also described.
