Simulation of 100 Gbps using Parallel Sequence Spread Spectrum modulation (PSSS) with 240 GHz radio

This paper assesses the impact of the imperfections in radio components on the delay spread and bit error rate (BER) by simulating both analog and digital domains. Parallel Sequence Spread Spectrum (PSSS) is used for physical layer (PHY) baseband technology, which considerably alleviates both transmitter and receiver design. Authors investigate the performance of the PSSS systems using a 240GHz transmitter and receiver radio. In the Mililink project [1] the 240 GHz RF (Radio Frequency) front-end was developed. The RF front-end parameters like e.g. power amplifier, mixer, striplines and low noise amplifier have been used in our baseband simulation models to emulate radio impairment losses. The BER is simulated for the PSSS modulation with several cyclic prefix and spectral efficiencies.
