WebFractional sampling (FS) has been investigated to achieve path diversity with a single antenna in an OFDM system. However, in the FS-OFDM system, it is necessary to oversample a received signal and it leads to large power consumption in a small terminal. To shift the signal processing burdens for FS from a receiver to a transmitter, a precoded … WebAug 17, 2024 · Methods, systems, and devices for wireless communication are described.

Webtransmitted on 1-4 co-boresighted beams for spatial diversity to mitigate fading. The beams are launched from 4 sub-apertures of OCTL’s 1-m telescope with a transmit beamwidth of 600µrad full-width half max. This wide beamwidth allows the telescope to illuminate the space terminal with open-loop pointing during the acquisition WebTransmit diversity is applied using Space-Frequency Block Coding (SFBC) and Frequency Switched Transmit Diversity (FSTD). Spatial multiplexing allows multiple antennas to transmit multiple independent streams and if the receiver also has multiple antennas, the streams can be separated out using space-time processing.
