摘要： A system and method are provided for Soft Interference Cancellation (SIC) in receiving Single Carrier Frequency Division Multiple Access (SC-FDMA) Multiple-Input Multiple Output (MIMO) signals. A receiver with Mr antennas accepts multicarrier signals transmitted simultaneously, with N overlapping carrier frequencies. The receiver removes a cyclic prefix (CP), and fast Fourier transforms (FFT) the multicarrier signal from each antenna, supplying Mr number of N-tone signals y. Using either parallel SIC (P-SIC) or successive SIC (S-SIC), interference is canceled in each of the Mr signals, and soft symbols are supplied for each of U layers. Interference is canceled using the P-SIC process by parallel processing the U layers in an i-th iteration, in response to feedback from an (i−1)th iteration. Alternatively, interference is canceled using the S-SIC process by sequentially processing the U layers in an i-th iteration, in the order of u0,u1, . . . , uU−1, using feedback generated from previously processed layers.

摘要： Binderless BaKX zeolitic adsorbents, methods for their production, and processes for their use in a liquid phase adsorptive separation process are provided. An adsorbent includes a binder-converted zeolite portion formed from x wt % kaolin clay binder and (100−x) wt % unconverted Zeolite X with a silica:alumina molar ratio of about 2.5. The kaolin clay binder is in the range of about 10 to about 20 wt %. Ba and K occupy cationic exchangeable sites within the adsorbent. K is in the range of about 0.25 to about 0.9% by weight and Ba is greater than about 31.6% by weight of the binderless BaKX zeolitic adsorbent. Cornstarch may be added to the Zeolite X and kaolin clay binder to increase adsorbent macro-porosity and pore volume. Productivity of the adsorbent is improved decreasing process operating costs. The mechanical strength of the adsorbent is also improved.

摘要： Provided are a system and method of estimating channels for a plurality of multicarrier signals in a wireless receiver. A receiver accepts a plurality of multicarrier signals, transmitted simultaneously from a plurality of transmitters, with overlapping carrier frequencies and nominally orthogonal reference signals. For each multicarrier signal, a reference signal is recovered including a plurality of adjacent subcarrier frequencies carrying predetermined symbols. A channel estimate is found across the plurality of adjacent subcarrier frequencies, for each multicarrier signal channel, by compensating for a loss of orthogonality between reference signals, in response to assuming a linear phase rotation for each channel across the plurality of adjacent reference signal subcarriers, and a constant amplitude for each channel across the plurality of adjacent reference signal subcarriers. More explicitly, the assumption of linear phase rotation and constant amplitude permits a Direction of Arrival (DoA) algorithm to be used.

摘要： Adsorbents and methods for the adsorptive separation of para-xylene from a mixture containing at least one other C8 aromatic hydrocarbon (e.g., a mixture of ortho-xylene, meta-xylene, para-xylene, and ethylbenzene) are described. Suitable binderless adsorbents (e.g., formulated with the substantial absence of an amorphous material that normally reduces selective pore volume), particularly those with a water content from about 3% to about 5.5% by weight, improve capacity and/or mass transfer. These properties are especially advantageous for improving productivity in low temperature, low cycle time adsorptive separation operations in a simulated moving bed mode.

摘要： The invention relates to a process for removing hydrogen halides from hydrocarbon-containing streams. More particularly, the invention relates to a process and an HCl sorbent for the removal of HCl and other hydrogen halides from hydrocarbon streams to prevent the formation of green oils. The sorbent has an increased capacity for the sorption of HCl and a reduced catalytic activity for the formation of green oils which, surprisingly, results from the pre-loading of water on a sodium promoted alumina adsorbent. The pre-loading of water on the sodium promoted alumina adsorbent in the range of about 5 to about 11 percent of the essentially water-free adsorbent increases the HCl sorption capacities by about 25% with a corresponding decrease in catalytic reactivity.
