Abstract:
This study compares quantitatively blind and training-based channel estimation for SDMA WLAN, from both a performance and complexity point of view. The semi-analytic simulations based on a ray-tracing channel model are presented. It is shown that the capacity reduction from training can be reduced to a negligible number of symbols, the training-based algorithm is more robust and the complexity of the blind algorithm exceeds the complexity of the training-based algorithm by one order of magnitude.
