论文摘要
在这项工作中，分析了无线传感系统中的高和中/低信噪比（SNR）方案，在这项工作中分析了矩形类似物源通道编码（AJSCC）的信号恢复性能。中/低SNR方案的分析和推导是基于矩形型AJSCC的三维信号映射曲线中所有信号变化案例的综合列表。均方根误差（MSE）性能的理论公式是针对具有矩形型AJSCC的模拟传感和数字传感系统的。评估结果表明，矩形型AJSCC中有最佳参数，以最大程度地减少在高和中/低SNR方案下的信号恢复MSE性能。此外，将数字传感与低分辨率类似物转换（ADC）的性能与这项工作中高和中/低SNR方案的模拟传感进行了比较。理论和评估结果具有基于矩形型AJSCC的无线传感系统设计的实用价值。
The signal recovery performance of the rectangular-type Analog Joint Source-Channel Coding (AJSCC) is analyzed in this work for high and medium/low Signal-to-Noise Ratio (SNR) scenarios in the wireless sensing systems. The analysis and derivations of the medium/low SNR scenario are based on the comprehensive listing of all the signal variation cases in the three-dimensional signal mapping curve of the rectangular-type AJSCC. Theoretical formulations of Mean Square Error (MSE) performance are derived for both analog sensing and digital sensing systems with rectangular-type AJSCC. Evaluation results indicate that, there are optimal parameters in the rectangular-type AJSCC to minimize the signal recovery MSE performance at high and medium/low SNR scenarios. In addition, the performance of digital sensing with low-resolution Analog-to-Digital Conversion (ADC) is compared with analog sensing for both high and medium/low SNR scenarios in this work. The theoretical and evaluation results have practical value to the wireless sensing system designs based on the rectangular-type AJSCC.
