Abstract
Spatial Multiplexing (SM) with Multiple Input Multiple Output (MIMO) is used in many communication systems for providing high data rates. While SM-MIMO is a powerful technique for increasing the data rate and bandwidth efficiency, the decoders for SM-MIMO are highly complex. The complexity grows exponentially for optimum decoders as the number of multiplexed layers in SM-MIMO increases. Many reduced complexity suboptimal methods are used in practice that have close to optimum performance but they remain highly complex causing high power consumption which is not desirable for battery operated client terminals. Due to the parallel architecture of many of the SM-MIMO decoders, they involve computations that may eventually turn out to be redundant. A method and apparatus may include identifying and eliminating potentially redundant computations in SM-MIMO decoders based on the technique referred herein as precomputation. The removal of redundant computations enables reduced power consumption for SM-MIMO decoders.
