Periodical power dropping effect in millimeter wave over fiber systems

In this paper, we generate millimeter carrier wave about 56 GHz, an simulation base on OptiSystem and experimental proof for the periodical power dropping of demodulated signal is proposed. The correspondent error vector magnitude (EVM) in different fiber length and bandwidth of long term evolution (LTE) electrical signal are also experimentally achieved to show how periodic power dropping affects the quality of demodulated signal. Finally, to prove our quality of demodulated signal, the constellations diagram of 16 QAM, 20 MHz wave carrier of demodulated signal are experimentally shown.
