    Abstract: Systems and methodologies are described that facilitate monitoring transmitter performance in a wireless communication environment. If the received modulation symbols are unknown during transmitter monitoring, it may be necessary to determine the modulation symbols for each subcarrier. The modulation types can be evaluated over a subset of subcarriers having a consistent modulation type, to reduce the possibility of an erroneous modulation type determination to an extremely low level. A metric can be generated for each modulation type that indicates the likelihood of a particular modulation type for the subset of subcarriers. The modulation type can be selected based upon the metric and modulation symbols consistent with the modulation type can be used for the subset of subcarriers.

    Abstract: A system and method are provided for generating bit log likelihood ratio (LLR) values for two-layered Quadrature Phase-Shift Keying (QPSK) turbo decoding in a wireless communications user terminal (UT). The method includes receiving a two-layered QPSK signal with an energy ratio that is unknown, but typically defined as either k 1 2 or k 2 2 . The method selects a mismatched energy ratio ( k 2 ) between k 1 2 and k 2 2 , and generating bit LLR values for two-layered QPSK turbo decoding, using the mismatched k 2 energy ratio. For example, if the received two-layered QPSK signal is known to have an energy ratio of about 4 or about 6.25. Then, k 2 is selected to be about 5.0625. Alternately stated, the mismatched k 2 energy ratio in selected by determining the approximate midpoint between k 1 2 and k 2 2 .

    Abstract: Elastomeric polymer blends and processes for their production are described. Specifically, the polymer blends comprise a first polymer and a second polymer, where the first polymer comprises from 70 wt% to 90 wt% units derived from propylene and from 10 wt% to 30 wt% units derived from ethylene and/or a C4-C10 alpha-olefin, and the second polymer comprises from 88 wt% to 98 wt% units derived from propylene and from 2 wt% to 12 wt% units derived from ethylene and/or a C4-C 10 alpha-olefin. The elastomeric polymer blends are further characterized by having two or more of the following properties: an overall propylene content of between 75 wt% and 90 wt%, a melting point between 110°C and 145°C, a Vicat softening point greater than 45°C, a tensile stress at 300% strain of less than 500 psi (3447 kPa), as determined by a stress strain test according to ASTM D412, or an average maximum force for pellet separation of less than 10 N in an accelerated storage stability test. The polymer blends are produced in a dual reactor process, in which the first polymer and the second polymer are prepared using differing catalyst systems.
