International Classification:

US Classification:

370351

Abstract:

Described is continuous network coding, in which a relay sends probability data comprising a continuous number for use as parity data. The node receives streams of bits sent from sources towards a destination, and computes the probability data based on current noise data and/or fading data. A selected set of the bits (all or some subset thereof) are combined, e.g., XOR-ed or concatenated, and send to the destination. Phase modulation is performed to convey probability information based on the probability data. The destination demodulates the signal to obtain the probability information, and combines the probability information with the data directly received from sources to perform joint decoding. The number of bits in the set of selected bits may be adaptively chosen based on current channel conditions, e.g., increased when the channel conditions from the sources directly to a destination are poor relative to the channel conditions via the relay.

Appl. No.:

International Classification:

G02F 1/13363

US Classification:

349 96

Abstract:

A display is provided that has upper and lower polarizers, a color filter layer, a liquid crystal layer, and a thin-film transistor layer. The color filter layer and thin-film transistor layer may be formed from materials such as glass that are subject to stress-induced birefringence. To reduce light leakage that reduces display performance, one or more internal layers may be incorporated into the display to help ensure that linearly polarized backlight that passes through the display is not undesirably converted into elliptically polarized light. The internal layers may include a thin-film polarizer layer that forms a coating on the color filter layer, a thin-film polarizer layer that forms a coating on the thin-film-transistor layer, a retarder layer that is formed as a coating on the color filter layer, and a retarder layer that is formed as a coating on the thin-film-transistor layer.
