论文摘要
集成和开火时间编码机（IF-TEM）是一种节能异步采样器。利用IF-TEM采样器进行带限的信号，我们在量化阶段之前介绍了时间编码和解码的时间编码和解码。在量化之前，根据编码信号的平稳性进行有效的模拟压缩，这是IF-TEM处理的基本特征。低位速率重建是通过将已知的IF-TEM动态范围细分为更紧密的窗口来实现的，该窗口可以固定尺寸或动态更改，并检测样品驻留在哪个窗口中。我们从经验上证明，使用相同数量的样品和多达7％的额外位置比常规IF-TEM导致MSE的5-20dB改善。使用压缩的IF-TEM固定重建MSE目标和样品数量，与经典IF-TEM相比，使用了压缩的IF-TEM可以使用1-2个较少的位。
An integrate-and-fire time-encoding-machine (IF-TEM) is an energy-efficient asynchronous sampler. Utilizing the IF-TEM sampler for bandlimited signals, we introduce designs for time encoding and decoding with analog compression prior to the quantization phase. Before the quantizer, efficient analog compression is conducted based on the stationarity of the encoded signal, which is a fundamental characteristic of IF-TEM processing. Low-bit-rate reconstruction is achieved by subdividing the known IF-TEM dynamic range into tighter windows, which can be either fixed size or dynamically changed, and detecting in which window the sample resides. We demonstrate empirically that employing the same number of samples and up to 7% additional bits than the conventional IF-TEM results in a 5-20dB improvement in MSE. Fixing the reconstruction MSE target and the number of samples, using the compressed IF-TEM enables the use of 1-2 fewer bits compared to the classical IF-TEM.
