Techniques to manage processing of multiple input multiple output communications

摘要

An apparatus may include a channel estimation component to determine a channel estimation matrix H for a tone of a multiplicity of tones in a multiple input multiple output (MIMO) communications signal. The apparatus may further include a processor circuit coupled to the receiver component, and a flow selection component for execution on the processor circuit to calculate a figure of merit for power loss for the received tone based upon the channel estimation matrix, and based upon the calculated figure of merit, perform either a max-log calculation or a maximum likelihood calculation to determine a received signal metric, but not both calculations. Other embodiments are described and claimed.

1. An apparatus, comprising:
a processor circuit; a channel matrix estimator for execution on the processor circuit to determine a channel estimation matrix H for a tone of a multiplicity of tones in a multiple input multiple output (MIMO) communications signal; and a flow selection component for execution on the processor circuit to:
form a Hermite HH conjugate of the channel estimation matrix;multiply the channel estimation matrix by the Hermite conjugate of the channel estimation matrix to form a product matrix HHH; andcalculate a figure of merit for power loss for the received tone from a ratio of a value determined from entries in the main diagonal of the product matrix HHH to a value determined from entries outside of the main diagonal HHH; andbased upon the calculated figure of merit, perform either a max-log calculation or a maximum likelihood calculation to determine a received signal metric, but not both calculations.
