Abstract
Techniques are presented for distributed processing Distributed-Input Distributed-Output (DIDO) wireless communication. A plurality of base stations (e.g., APs) are provided, each configured to wirelessly serve one or more wireless devices (e.g., clients). At least first and second base stations are configured to transmit simultaneously at an agreed upon time. The first and second base stations are each configured to locally generate steering matrix information used to spatially precode their respective data transmissions in order to steer their respective data transmissions to their one or more wireless devices while nulling to the one or more client devices of the other base station. Moreover, the first and second base stations are each configured to locally generate a transmit waveform by applying the steering matrix information to their respective data transmissions.
