Systems and methods are described for radio frequency (RF) calibration in a multiple antenna system (MAS) with multi-user (MU) transmissions ('MU-MAS') exploiting uplink/downlink channel reciprocity. The RF calibration is used to compute open-loop downlink precoder based on uplink channel estimates, thereby avoiding feedback overhead for channel state information as in closed-loop schemes. For example, a MU-MAS of one embodiment includes a wireless cellular network with one or multiple beacon stations, multiple client devices and multiple distributed antennas operating cooperatively via precoding methods to eliminate inter-client interference and increase network capacity.

An apparatus and method are described for capturing images in visible light as well as other radiation wavelengths. In one embodiment, the apparatus comprises: a diffraction coded imaging system including a plurality of apertures arranged in a diffraction coded array pattern with opaque material blocking array elements not containing apertures; and a light- or radiation-sensitive sensor coupled to the diffraction coded imaging system array and positioned at a specified distance behind the diffraction coded imaging system array, the radiation-sensitive sensor configured to sense light or radiation transmitted and diffracted through the apertures in the diffraction coded imaging system array.

A system and method are described below for encoding interactive video used in video games streamed from a server to a client. For example, one embodiment of a computer-implemented method for performing video compression, and detecting a maximum data rate of a communication channel between a server and a client. The method includes transmitting a video stream comprising a series of compressed frames from the server to the client. The method includes detecting that the maximum data rate will be exceeded if a particular frame or frames of the sequence of frames are transmitted from the server to the client over the communication channel. The method includes reducing the frame rate of the video stream by adjusting compression of the video frames being sent from the server to the client to avoid exceeding the maximum data rate.

For example, a method implemented within a wireless transmission system comprised of a plurality of wireless client devices and a plurality of distributed antennas is described comprising: computing channel state information (CSI) for wireless communication channels between the plurality of base distributed antennas and the wireless client devices; computing precoding weights from the channel state information; precoding data using the precoding weights prior to wireless transmission from the plurality of distributed antennas to the wireless client devices; and wirelessly transmitting the precoded data from the distributed antennas to each of the wireless client devices, wherein the precoding causes radio frequency interference between the plurality of base stations but simultaneously generating a plurality of non-interfering radio frequency user channels between the plurality of distributed antennas and the plurality of wireless client devices.
