研究目的
To demonstrate wireless communication measurements at serial data-rates up to 20 Gb/s using a III-V wavelet generator with sub-period start-up and off-the-shelf V-band components in waveguide assemblies.
研究成果
Wireless OOK communication at up to, unprecedented, 20 Gb/s serial data-rates have been demonstrated. The utilised III-V transmitter front-end has high energy-efficiency and long link distances were achieved, as compared to state-of-the-art integrated multi-Gb/s transceivers. Viable performance was measured over channel distances up to 1.5 m at data-rates of 10 and 15 Gb/s for bit-error rate ke < 10?5 and 10?3, respectively.
研究不足
The performance was limited by the closing of the symbol eye at higher data-rates, attributed to the symbol transition-time being of approximately the same length as the UI. The receiver power dissipation was high, as compared to state-of-the-art.
1：Experimental Design and Method Selection:
The transceiver was implemented using an Anritsu MP1800A Signal Quality Analyzer equipped with a 32-Gb/s pulse pattern generator and a high-sensitivity error detector. No clock-recovery was implemented and the clock was wired directly from the PPG to the ED.
2：Sample Selection and Data Sources:
An n = 2N ?1 = 231 ?1 bit pseudo-random binary sequence (31-PRBS) of data with high and low levels of +
3：6 and ?6 V, respectively, was fed to the probed V-band transmitter front-end. List of Experimental Equipment and Materials:
A coherent RTD-MOSFET wavelet generator with sub-period start-up and quench was used to up-convert the input baseband data-pattern to the V-band. The output of the wavelet generator was probed with an RF-probe and the signal was then fed to a 20-dBi gain V-band horn antenna via a bias-T and an adapter.
4：Experimental Procedures and Operational Workflow:
The signal was sent over a line-of-sight channel at link distances of d =
5：3, 6, 9, 2 and 5 m. Data Analysis Methods:
The received energy detector output signal was synchronised to find the ideal sampling point within the symbol UI. A total of number of m = 1010 bits were evaluated for each measurement.
