Energy profiling of FPGA-based PHY-layer building blocks encountered in modern wireless communication systems

Abstract

Proceeding at: IEEE 8th Sensor Array and Multichannel Signal Processing Workshop (SAM), took place 2014, Jun, 22-25 in Coruña (españa). The event web site of http://www.gtec.udc.es/sam2014/ . ; Characterizing the energy cost of different physical (PHY) layer building blocks is becoming increasingly important in modern cellular-based communications, considering the cross sector requirements for performance enhancements and energy savings. This paper presents energy profiling metrics of different PHY-layer FPGA implementations encountered in modern wireless communication systems. The results give an insight of the distribution of the consumed energy in different baseband building blocks or configurations before and after applying power optimizations in the FPGA design and implementation. ; This work was partially supported by: the Spanish Government under projects TEC2011-29006-C03-01 (GRE3N-PHY), TEC2011-29006-C03-02 (GRE3N-LINKMAC) and TEC2011-29006-C03-03 (GRE3N-SYST); and the European Commission under project NEWCOM# (GA 318306). ; Publicado
