A 477mW NoC-based digital baseband for MIMO 4G SDR

Abstract

A MIMO 3GPP-LTE digital baseband chip based on a heterogeneous 3 × 5 array NoC using 3.2 GOPS/50 mW programmable VLIW cores is presented. It features less than 10 ¿s run-time full physical layer reconfiguration and distributed power management leading to 477 mW power consumption on a 4 × 2 MIMO RX application.
