The research on detection algorithms for uplink multiuser Massive multi input multi output (MIMO) system is a hot-spot for 5G. The recent detection algorithms are constrained by the assumed condition that the receiving antennas' number should be equal to or larger than the transmitting antennas' number. For the overloaded case that the total number of transmitting antennas of users in a cell is larger...
Spoofing attacks are one of the most dangerous threats for the application of the global navigation satellite system (GNSS), especially for autonomous driving and unmanned aerial vehicles. In this paper, we present a more robust spoofing mitigation algorithm based on subspace projection that is independent of the number of antennas and that can be utilized in single-antenna GNSS receivers. During...
This paper proposes a new type of complementary code, i.e., 3-D complementary code (3DCC), which integrates space–time coding and code division multiple access under a unified framework for multiple-input–multiple-output (MIMO) system implementation. Owing to its ideal correlation properties, the 3DCC ensures orthogonal transmissions among users and antennas. Analytical studies given in this paper...
There has been an increasing attention on cooperative diversity, which is a method to allow a single-antenna mobile to share other mobiles' antennas and thus achieve transmit diversity. The use of multiple-antennas, however, has been identified as a certain trend for high-rate transmissions over wireless channel. In this paper, we investigate the uplink performance of a single-relay cooperative scenario...
