Abstract— In this paper a simulation framework to analyze, design and optimize the physical layer
of IEEE 802.11ac wireless local networks focusing on multi-user operation scenario is described
and validated. The performance of channel inversion, regularized channel inversion and block
diagonalization recoding schemes with zero forcing and minimum mean squared error multiple
input multiple output (MIMO) detectors is evaluated over different configurations of 802.11 Task
Group n (T Gn) and T Gac channel models. The expressive power loss due to multi-user operation
has shown that more advanced pre coding and MIMO detection schemes must be designed to allow
satisfactory operation into feasible signal-to-noise-ratio ranges.
Existing method:
MIMO-OFDM
Proposed method:
The performance of channel inversion, regularized channel inversion and block diagonalization
recoding schemes with zero forcing and minimum mean squared error multiple input multiple
output (MIMO) detectors is evaluated over different configurations of 802.11 Task Group n (T
Gn) and T Gac channel models.
Merits:
Better output
feasible signal-to-noise-ratio ranges
Demerits:
1. time process is very high.
