  • Publication number: 20100203917
    Abstract: Techniques are described that can be used to determine a transmitter power level of a mobile station based on spectrum efficiency gain and loss. Spectrum efficiency gain is measured for a home sector base station. Spectrum efficiency loss is measured for base stations other than the home sector base station. In one example, a base station transmits information such as noise plus interference level to a mobile station and the mobile station determines the transmitter power level. In another example, the mobile station transmits information such as preamble signal strength and preamble total signal strength to the home sector base station and the home sector base station determines the transmitter power level and instructs the mobile station to apply the determined transmitter power level.

  • Publication number: 20090323513
    Abstract: A weighted tone reservation (WTR) method and system are disclosed, for PAPR reduction. The WTR method solves the peak re-growth problem with minimum overhead. By avoiding the drawbacks of conventional tone reservation approaches, systems employing the WTR method may experience a significant PAPR reduction. The WTR method may be applied to next generation OFDMA-based wireless broadband technologies to increase system throughput and cell coverage.

  • Publication number: 20090274103
    Abstract: A peak-to-average power ratio (PAPR) reduction method, known as system-aided PAPR reduction (SAPR), is disclosed. Based on a TR algorithm, the SAPR method avoids the drawbacks of conventional tone reservation implementations, and reduces PAPR significantly, in some embodiments. The SAPR method may be applied to next generation OFDMA-based wireless broadband technologies, to increase system throughput and cell coverage.

  • Publication number: 20090178032
    Abstract: In an example data mining process, performance data for instructions that execute in a data processing system is obtained. The performance data may comprise instruction addresses and corresponding performance information. A dump that comprises the instructions and corresponding instruction addresses may also be obtained. Common code segments in the dump may be automatically identified. A common code segment may comprise an ordered set of multiple instructions that appears multiple times in the dump. Aggregate performance data for the common code segments may be generated, based at least in part on (a) the instruction addresses associated with the common code segments in the dump, and (b) the instruction addresses and the corresponding performance information from the performance data. Other embodiments are described and claimed.

  • Patent number: 7447263
    Abstract: A method includes receiving an original string of bits where each of the bits represents one of two possible logic levels. The string of bits also carries information. A new string is formed, based on the original string, which contains all of the information of the original string by using fewer bits of one of the logic levels.

  • Patent number: 7190788
    Abstract: The methods and apparatus described herein encrypt an unencrypted binary string using an encryption key and a varying-radix conversion method. The encryption key is used to parse the unencrypted binary string into unencrypted sub-strings. The varying-radix conversion method is used to transform the unencrypted sub-strings into encrypted sub-strings. The encrypted sub-strings may then be concatenated together to produce an encrypted binary string. In addition, the reverse process is employed to recover the unencrypted binary string from the encrypted binary string. For example, the decryption process may occur after the encrypted binary string is transmitted over a network communications system.

  • Publication number: 20060095675
    Abstract: A three-stage hybrid stack model includes two separate stages of registers, or in other words, two register stacks. Below the two register stages is a memory stage, or memory stack. As operands are pushed onto the top register stack, operands residing in registers are moved down to accommodate the new operands. A second register stack, or transfer register stack receives overflow from the top register stack and supplies operands to the top register stack when the top register stack is underflowed. A third stage made up of memory locations is used to store overflow from the transfer register stack. The memory stack also supplies operands to the transfer register stack as needed.
