An energy efficient weakly programmable MIMO detector architecture

[摘要] Energy efficient processing is mandatory in todays' mobile devices.For the upcoming multiple-antenna systems, algorithmic flexibility enablesthe dynamic reaction to changing channel conditions.We show that most of the tree search based MIMO detection algorithms are based on the samealgorithmic kernelsand present a weakly-programmable architecture based on these observations.In this way, the detection algorithm can be chosen and parameterized during runtime accordingto the current channel conditions and QoS requirements leading to a highly energy efficient implementation.The architecture has been implemented and synthesized on a 65 nm technology, resulting in anarea of 0.26 mm² and a power consumption of only 15 mW.
