【Compress-Decompress algrithms】 224071252zuixinwenzhang DL : 0: 离散余弦变换(DCT)是一种常用的数字速率变换编码方法。DCT首先将整个图像分割成n×n像素块,然后在n×n像素块上逐帧执行DCT变换。由于图像的高频成分很小,与高频分量对应的系数通常为零,肉眼对高频分量的变化并不敏感, 因此,我们使会用简洁的定量方法。因此,数字传输系数的速率远小于用于传输图像像素的数字速率。到达接收机后,逆离散余弦变换返回到样本值。虽然会有一定的失真,但人眼是可以接受的。(The coefficients of the DCT domain motion compensation error or the original image information convert into blocks are represented by different frequency components. It has two advantages: first, signal 1, most of the energy in the small range is concentrated in the frequency domain. Such a description is an important part of several key points. Second, mapping the frequency domain decomposition process to the human visual system.)

【AI-NN-PR】 Deep Learning Based Communication Over the Air DL : 0: 通信系统的端到端学习是a 引人入胜的新颖概念迄今为止仅被验证模拟基于块的传输。它允许学习发射机和接收机实现为深度神经网络（NN），它们针对任意可区分的端到端进行了优化 performancemetric，例如块错误率（BLER）。在本文中，我们证明无线传输是可能的：我们建造，训练，并运行完整的通讯系统的神经网络使用非同步的现成软件定义无线电和开源深度学习软件库。(End-to-end learning of communications systems is a fascinating novel concept that has so far only been validated by simulations for block-based transmissions. It allows learning of transmitter and receiver implementations as deep neural networks (NNs) that are optimized for an arbitrary differentiable end-to-end performancemetric, block error rate (BLER). In this paper, we demonstrate that over-the-air transmissions are possible:We build, train, and run a complete communications system solely composed of NNs using unsynchronized off-the-shelf software-defined radios and open-source deep learning software libraries.)
