Demo: FPGA implementation of an IEEE802.15.4g MR-OFDM baseband modem for smart metering utility networks

This demo presents the implementation of an MR-OFDM baseband modem, in FPGA, compliant with the recently released IEEE802.15.4g standard. Such standard is devoted to Smart Metering Utility Networks. The modem was designed using VHDL and prototyped on Altera´s device 5CGXFCC5C6F27C7N. The prototype supports all MR-OFDM configurations and its maximum FPGA speed is 65.16 MHz. The modem was evaluated as follows: parameters measured by an Electronic Energy Meter (active power, reactive power, current, voltage and frequency) were used at the transmitter side, the transmitted signal was corrupted by the wireless channel and AWGN, and then processed by the OFDM receiver.
