Abstract :
This paper describes the implementation of an energy-efficient digital SDR baseband platform. The multi processor system-on-chip (MPSOC) is implemented in 90nm CMOS technology and occupies 32mm2. It incorporates all digital signal processing required by the physical layer of the WiFi(802.11n), WiMax(802.16e), mobile TV and 3GPP-LTE standards. The heterogeneous architecture with hierarchical wake-up achieves 5mW idle time power, is capable of delivering a net data rate in excess of 200Mbps and consumes 231mW during 108Mbps WLAN 2×2 MIMO Rx, achieving 2.14nJ/b energy efficiency.
