This paper presents the transmission of broadband complex modulated signals with data rates up to 64Gbit/s using an analog front-end based on monolithic microwave integrated circuits (MMICs) at a carrier frequency of 300GHz.Abstract:
This paper presents the transmission of broadband complex modulated signals with data rates up to 64Gbit/s using an analog front-end based on monolithic microwave integrated circuits (MMICs) at a carrier frequency of 300GHz. Besides the typical modulation formats like BPSK, QPSK, and 16QAM a non-common modulation format 8APSK is introduced and measured. The maximal transmitter symbol rate is 32Gbd. The signal quality is evaluated in terms of error vector magnitude, which shows values of −10.8dB for BPSK and −10.10dB for QPSK at a symbol rate of 32Gbd and values of −14.8dB for 16QAM at a symbol rate of 2Gbd.read more
