摘要： An apparatus for sequential deposition of an intermixed thin film layer and a sublimated source material on a photovoltaic (PV) module substrate is provided, along with associated processes. The process can include introducing a substrate into a deposition chamber, wherein a window layer (e.g., a cadmium sulfide layer) is on a surface of the substrate. A sulfur-containing gas can be supplied to the deposition chamber. In addition, a source vapor can be supplied to the deposition chamber, wherein the source material comprises cadmium telluride. The sulfur-containing gas and the source vapor can be present within the deposition chamber to form an intermixed layer on the window layer. In one particular embodiment, for example, the intermixed layer generally can have an increasing tellurium concentration and decreasing sulfur concentration extending away from the window layer.

摘要： An apparatus and related process are provided for vapor deposition of a sublimated source material as a doped thin film on a photovoltaic (PV) module substrate. A receptacle is disposed within a vacuum head chamber and is configured for receipt of a source material supplied from a first feed tube. A second feed tube can provide a dopant material into the deposition head. A heated distribution manifold is disposed below the receptacle and includes a plurality of passages defined therethrough. The receptacle is indirectly heated by the distribution manifold to a degree sufficient to sublimate source material within the receptacle. A distribution plate is disposed below the distribution manifold and at a defined distance above a horizontal plane of a substrate conveyed through the apparatus to further distribute the sublimated source material passing through the distribution manifold onto the upper surface of the underlying substrate.

摘要： A method of decoding a plurality of diverse signals for low-density parity-check (LDPC) decoders that takes advantage of signal diversity. The method allows for the combining of soft-decision LDPC encoded non-coherently modulated signals, which is in contrast to existing approaches where hard decision combining is used for non-coherently modulated signals. The method includes the steps of inputting each diversity signal into a unique demodulator, and calculating the LLR of each demodulated signal. When the diverse demodulated signals are combined into a single combined signal, each bit of the combined signal is selected according to the value of either the highest LLR value of each bit across the demodulated signals or according to the sum of the LLR of each bit across the demodulated signals.

摘要： A wireless device with power amplifiers having different characteristics to support transmission on multiple antennas is disclosed. These power amplifiers may have different gain, different maximum output power levels, etc. in order to meet requirements of different wireless systems. In an exemplary design, an apparatus includes first and second power amplifiers having different characteristics. The first power amplifier amplifies a first input signal and provides a first output signal for a first antenna. The second power amplifier amplifies the first input signal or a second input signal and provides a second output signal for a second antenna, e.g., in a MIMO mode or a transmit diversity mode. Only the first or second power amplifier amplifies another input signal and provides another output signal to the first antenna, e.g., in a CDMA mode or a GSM mode.
