A simple scheme for spatially multiplexing two BPSK signals using a switched antenna system with a single RF chain, a shared RF-DC cable and a shared RF-DC feeding circuit is proposed. The idea is to modulate the first BPSK substream to one of the two array elements while exciting the second element parasitically by the field of the first one. The second substream is encoded in such a way to control...
This paper addresses the combination of spatial multiplexing (SM) with space-frequency block coding (SFBC) for SCFDE systems, in high mobility environment. Coding across different antennas and different subcarriers, such as SFBC, is more suitable than space-time block coding (STBC) in high-mobility environments of interest for future wireless systems. However, the application of SFBC schemes to SCFDE...
