    Abstract: A Multi-User-Multiple Input Multiple Output (MU-MIMO) transmission method performed by an AP in a Wireless Local Area Network (WLAN) system is provided. The method includes transmitting an MU-MIMO initiation message to a destination STA which is a target of a MU-MIMO transmission, the MU-MIMO initiation message informing that MU-MIMO transmission will be initiated, receiving a sounding frame transmitted by the destination STA as a response to the MU-MIMO initiation message and performing MU-MIMO transmission on data by beamforming based on channel information obtained from the sounding frame. The sounding frame includes precoded and virtualized channel information Hvirtual between the AP and the STA. A dimension of the Hvirtual is lower than a dimension of channel information H between the AP and the STA.

    Abstract: Signal separation techniques based on frequency dependency are described. In one implementation, a blind signal separation process is provided that avoids the permutation problem of previous signal separation processes. In the process, two or more signal sources are provided, with each signal source having recognized frequency dependencies. The process uses these inter-frequency dependencies to more robustly separate the source signals. The process receives a set of mixed signal input signals, and samples each input signal using a rolling window process. The sampled data is transformed into the frequency domain, which provides channel inputs to the inter-frequency dependent separation process. Since frequency dependencies have been defined for each source, the process is able to use the frequency dependency to more accurately separate the signals. The process can use a learning algorithm that preserves frequency dependencies within each source signal, and can remove dependencies between or among the signal sources.
