A method of providing fully automated processing of a Split Lot of wafers to manufacture semiconductor devices is provided. The method processes a test Lot of wafers with a production Lot. Processing of both Lots continue as a single Lot along the production processing path up to a split condition process. Processing of the production Lot is put on hold until the alternate processing or test Lot processing is completed. The two Lots are then merged and processed according to the original predefined process steps continue on both Lots.

A method for optimizing the rate at which a given acid should be injected into a carbonate-containing rock formation during an acid injection process. The first step of the method calculates the Damkohler numbers for regimes in which kinematic force, diffusion rate and reaction rate control. The Damkohler numbers are then used to calculate the rate of growth of wormholes as a function of flux, taking into account compact dissolution, wormholing, and uniform dissolution. The calculated function is used to calculate an optimum flux for the formation. The optimum flux is then used to calculate an optimum injection rate at a given point in the acid injection process.

A method for decoding and checking a tail-biting convolutional code is provided. The method fully utilizes structural features of the tail-biting convolutional code to re-sort Log-Likelihood Ratio (LLR) values input into a decoder, and by reconstructing a derivative generator polynomial of a convolutional code, allows the decoder to output in serial according to a normal ordering of information bits during backtracking, that is, a first bit of an information sequence is first decoded successfully. Thus, CRC checking may be activated as soon as possible, so that part of the backtracking process and the CRC checking may be performed in parallel, thereby achieving the objective of reducing a processing time delay in decoding and checking the tail-biting convolutional code.

The present invention discloses a method for service data transmission, a receiver, a mobile terminal, a transmitter and a base station. In the above method, a receiver of a mobile terminal receives a control signal sent by a base station, wherein the control signal is used for indicating more than one subcarriers allocated to the mobile terminal and the more than one subcarriers are used for service data transmission; it is judged whether the difference between the highest frequency FREHigh and the lowest frequency FRELow in the more than one subcarriers exceeds a threshold value THB; if not exceed, then the receiver receives service data using a narrowband mode, otherwise receives the service data using a broadband mode. By way of the technical solution of the present invention, the signal bandwidth processed by the receiver can become narrow, the digital sampling rate becomes lower, the calculation amount of the FFT module and relevant storage are reduced, thus achieving the effect of reducing the power consumption overhead of the mobile terminal.

The disclosure fully utilizes structural features of the tail-biting convolutional code to re-sort Log-Likelihood Ratio (LLR) values input into a decoder, and by reconstructing a derivative generator polynomial of a convolutional code, allows the decoder to output in serial according to a normal ordering of information bits during backtracking, that is, a first bit of an information sequence is first decoded successfully. Thus, CRC checking may be activated as soon as possible, so that part of the backtracking process and the CRC checking may be performed in parallel, thereby achieving the objective of reducing a processing time delay in decoding and checking the tail-biting convolutional code. The disclosure does not increase any hardware expense, belongs to an improvement of low cost, and does not cause any decoding performance downgrade.

The time slot index for wireless signals is synchronized using an approach that facilitates rapid synchronization acquisition and tracking synchronization recovery. According to an example embodiment, a synchronization circuit (e.g., 300) uses data in symbols of a particular signal frame (e.g., 120) to set a time slot index synchronization characteristic for an acquired wireless signal, and further to track time slot index synchronization during processing of the signal.
