Key solutions and standardization progress for transmission enhancement in Rel-19 NR NTN

Dianxin kexue
By adaptively enhancing the terrestrial 5G new radio (NR) protocol for satellite communication scenarios, 3GPP non-terrestrial network (NTN) fully integrates the advantages of terrestrial and non-terrestrial networks with continuous evolution capability,

Modulation-mode assignment for SVD-assisted and iteratively detected downlink multiuser MIMO transmission schemes

, 2011
In this contribution we jointly optimize the number of multiple-input multiple-output (MIMO) layers and the number of bits per symbol within an iteratively-detected multiuser MIMO downlink (DL) transmission scheme under the constraint of a given fixed ...

A 15.3 GHz satellite-to-ground diversity experiment utilizing the ATS-5 satellite

, 1972
During 1970 and 1971 the characteristics of a diversity satellite-to-ground communication link were measured using the ATS-5 15.3 GHz downlink. These data were gathered at two ground receiving terminals spaced 4 km apart during 1970 and 8 km apart during
