基于WiMAX的数字射频光纤传输仿真与分析
Simulation and Analysis of WiMAX-based Digital RF Transmission Over Optical Fiber
摘要
Abstract
Based on the simulation model of digital RF transmission over optical fiber (DRoF) at the standard of WiMAX, this paper establishes a math model for the links of input signals, ADC sampling, holding and quantizing, transmitting over the optical fiber, detection and making decision as well as DAC zero-order holding, demodulation output and etc., and implements the whole process of WiMAX signals transmission over the links of DRoF. The impacts mechanism of ADC resolution, ADC and DAC clock jitter noise, optical noise and other single-factors on the system performance are experimented by simulation, and the influences of the bit rate in the condition of WiMAX signal transmission on the error rate, error vector amplitude and other performance indices are also analyzed in this paper. The conclusion drawn can provide the theoretic analysis basis for the study and optimization of DRoF links.关键词
