Geometric Accuracy Evaluation of GF-7 Image
2021 IEEE International Geoscience and Remote Sensing Symposium IGARSS, 2021We selected a scene of “GF-7” satellite multispectral rear-view camera image in Chengdu, Sichuan Province of China. At the same time, we take 26 high-precision GPS sampling points evenly distributed in the region as control points, and make statistics on the geometric positioning accuracy of images.

Some high-rate linear codes over GF(5) and GF(7)
Problems of Information Transmission, 2007Let an [n, k, d] q code be a linear code of length n, dimension k, and with minimum Hamming distance d over GF(q). The ratio R = k/n is called the rate of a code. In this paper, [62, 53, 6]5, [62, 48, 8]5, [71, 56, 8]5, [124, 113, 6]5, [43, 36, 6]7, [33, 23, 7]7, and [27, 18, 7]7 high-rate codes and new codes with parameters [42, 14, 19]5, [42, 15, 18 ...

Existence and classification of NMDS codes over GF(5) and GF(7)
2000The maximum lenght of a NMDS [n,k,d]_q code is denoted by m'(k,q). It has been verified that m'(4,7)=14 and m'(5,7)=13. Moreover the NMDS codes of sizes m'(5,5), m'(6,5), m'(7,5) and m'(4,7) have been classified.
