IFFT Stage-dependent Minimum Bit Resolution Maps for Real-time Optical OFDM Transceivers

Not Accessible

Your library or personal account may give you access

Abstract

To significantly reduce the FPGA/ASIC resource usage in OOFDM transceivers, numerical identifications and experimental verifications are undertaken, for the first time, of an optimum map of minimum bit-resolutions of different IFFT stages against DAC resolutions.
