Abstract
Varying embodiments of the present invention provide a MIMO apparatus, such as a transceiver and a method of operation thereof. In an embodiment, the transceiver employs a parallelized., two-stage pipeline architecture that reduces the overall latency of the system. This reduction in latency translates to cost savings and higher data rates for the same hardware clock speed.
Claims28
A method of operating a multiple input multiple output (MIMO) decoder comprising:
- (a) receiving a plurality of spatial streams wherein the plurality of spatial streams comprise inphase (I) and quadrature (Q) pairs of streams;
- (b) calibrating the I and Q pairs of the plurality of streams;
- (c) decomposing the calibrated I and Q pairs of the plurality of streams, wherein each of the calibrated decomposed I/Q pairs of streams comprises a plurality of symbols;
- (d) searching each of the plurality of symbols thereby forming a search subset;
- and
- (e) systematically pruning the search subset based on a predetermined set of criteria.
A computer program product tangibly embodied on a computer usable medium for controlling user access to stored data elements, the computer program product having computer readable program means for causing a computer to perform the acts of:
- (a) receiving a plurality of spatial streams wherein the plurality of spatial streams comprise inphase (I) and quadrature (Q) pairs of streams;
- (b) calibrating the I and Q pairs of the plurality of streams;
- (c) decomposing the calibrated I and Q pairs of the plurality of streams, wherein each of the calibrated decomposed I/Q pairs of streams comprises a plurality of symbols;
- (d) searching each of the plurality of symbols thereby forming a search subset;
- and
- (e) systematically pruning the search subset based on a predetermined set of criteria.
A MIMO transceiver comprising;
- a calibration module for:
- receiving a plurality of spatial streams wherein the plurality of spatial streams comprise inphase (I) and quadrature (Q) pairs of streams and;
- calibrating the I and Q pairs of the plurality of streams;
- a decomposition module coupled to the calibration module for decomposing the calibrated I and Q pairs of the plurality of streams wherein each of the calibrated decomposed I and Q pairs of the plurality of streams comprises a plurality of symbols;
- and
- a sorting module coupled to the decomposition module for searching each of the plurality of symbols thereby forming a search subset and systematically pruning the search subset based on a predetermined set of criteria.
