Architecture design and implementation of key components of an OFDM transceiver for IEEE 802.15.4g
This work proposes a transceiver architecture for the OFDM PHY of IEEE802.15.4g standard targeting Smart Metering Utility Networks. It also details the main components implemented for preliminary hardware prototyping. The OFDM transceiver is part of a project that is under development and aims to implement in ASIC the three PHYs defined by the IEEE802.15.4g standard, i.e. MR-FSK, MR-OQPSK and MR-OFDM. The OFDM baseband transmitter is complete. For the baseband receiver, the main components for frame synchronization and equalization, as well as for decoding the data, have been already implemented. The transceiver was designed using VHDL and prototyped on Altera's device 5CGXFCC5C6F27C7N.
