Optimal PPDU Duration Algorithm for VHT MU-MIMO Systems

We propose an optimal Physical Layer Convergence Procedure Protocol Data Unit (PPDU) duration algorithm that divides a long data stream into two portions among consecutive groups based on the average PPDU duration of the Very High Throughput (VHT) group. The proposed solution considers all Wireless Local Area Network (WLAN) parameters and satisfies requirements of the VHT Multi-User Multiple Input Multiple Output (MU-MIMO) protocols. The simulation results show that the optimal PPDU duration algorithm offers significant improvements by accommodating traffic of additional STAs in shorter time and by efficiently utilizing the previously wasted sections of space-time streams.
