C3 Scalable THz Transceiver Impairment Model

我们联合收割机了第一阶段子项目A3，B2和B3的测量和建模结果，并使用它们来组成THz发射机，THz接收机和超宽带采样的综合模型。该模型将包括所有主要损伤，如RF带宽、放大器和混频器非线性、加性噪声、LO相位噪声、采样抖动、采样带宽、有效分辨率等。该模型将在Matlab/Simulink和Keysight ADS中实现，并允许与ADS和Simulink进行联合仿真，同时我们还将研究时间和频率分辨率与计算效率之间的权衡。收发器实验、电子和光电频率合成器实验以及电子和光学采样实验的测量结果将用于校准模拟模型，以便能够量化损伤并根据真实数字评估收发器性能。使用测量结果校准仿真模型后，将移交给系统级子项目（C1、C2）和子项目T。我们还将使用参数化的收发器损伤模型来系统地研究不同损伤对EVM和BER的影响，这取决于整体系统参数，例如RF带宽、调制方案、波特率、采样率等。

We combine the measurement and modeling results from sub-projects A3, B2 and B3 in phase 1 and use them to compose a comprehensive model of the THz transmitter, the THz receiver, and ultrabroadband sampling. The model will include all major impairments such as RF bandwidth, amplifier and mixer non-linearities, additive noise, LO phase noise, sampling jitter, sampling bandwidth, effective resolution etc. The model will be implemented in Matlab/Simulink and Keysight ADS and shall allow co-simulation with ADS and Simulink, while we will also investigate the tradeoffs between time and frequency resolution and computational efficiency. Measurements from transceiver experiments, experiments with electronic and optoelectronic frequency synthesizers, as well as electronic and optical sampling experiments will be used to calibrate the simulation model in order to be able to quantify the impairments and to assess transceiver performance based on realistic figures. After the calibration of the simulation model with measurement results it will be handed over to sub-projects on system level (C1, C2) and to sub-project T. We will also use the parameterized transceiver impairment model to systematically study the influence of the different impairments on EVM and BER, depending on overall system parameters such as RF bandwidth, modulation schemes, Baud rate, sampling rate etc.
