Abstract
Systems and methods are described herein for communications bandwidth enhancement using Orthogonal Spatial Division Multiplexing (OSDM). For example, large sparse antenna arrays may be able to distinguish between signals emitted by multiple nearly collocated antennas, even if the signals have the same frequency, polarization, and coverage. Thus, the use of a large sparse antenna array may be able to resolve/isolate individual antennas on a single platform, allowing for OSDM, analogous to Orthogonal Frequency Divisional Multiplexing (OFDM). Using OSDM, multiple antennas on the same vehicle are able to reuse the same frequencies/polarizations without interference, thereby increasing spectrum availability while still providing the same transmitter power spectral density and total RF power emission.
