Abstract
Embodiments of the invention provide various methods for detecting a spatial division multiple access (SDMA) channel swap. A first SDMA communication channel is assigned to a first user terminal that initially transmits its signal over the first SDMA communication channel. A second SDMA communication channel is assigned to a second user terminal that initially transmits its signal over the second SDMA communication channel. The first user terminal's signal and the second user terminal's signal are analyzed to determine that the first user terminal is transmitting its signal over the second SDMA communication channel and the second user terminal is transmitting its signal over the first SDMA communication channel.
