摘要： A system including a variable gain amplifier, an automatic gain control module, and a channel estimation module. The variable gain amplifier amplifies an input signal in accordance with a gain. The input signal includes a plurality of orthogonal frequency domain multiplexing symbols. Each of the plurality of orthogonal frequency domain multiplexing symbols is preceded by a respective cyclic prefix. The automatic gain control module adjusts, based on a signal strength of the input signal, the gain of the variable gain amplifier during the respective cyclic prefix preceding each of the plurality of orthogonal frequency domain multiplexing symbols. The automatic gain control module generates a control signal in response to the gain of the variable gain amplifier being adjusted. The channel estimation module generates a channel estimate for each of the plurality of orthogonal frequency domain multiplexing symbols and updates the channel estimate based on the control signal.

摘要： In a method for synchronizing a receiver to a synchronous signal, in a signal having been processed based on an automatic gain control (AGC) with a varying gain, a symbol is detected. An estimated beginning of a subsequent frame is determined based on the detected symbol. A gain of the AGC is fixed for a period during which the estimated start of the subsequent frame is processed by the AGC. A transform of the signal is analyzed to determine if the estimated start of the subsequent frame corresponds to an actual start of the subsequent frame. If the estimated start of the subsequent frame does not corresponds to the actual start of the subsequent frame, the gain of the AGC is allowed to resume varying and, a further symbol in the signal is detected, the signal having been processed based on the varying gain of the AGC.

摘要： In a method for synchronizing a receiver to a synchronous signal, a plurality of potential symbols are detected in a signal, the signal having been processed based on automatic gain control (AGC) with a varying gain. Next frame potential symbols corresponding to potential symbols in the plurality of potential symbols are determined, the next frame potential symbols being in frames subsequent to the frames in which the corresponding potential symbols are located. A gain of the AGC is fixed for each corresponding symbol interval during which a next frame potential symbol is operated on by the AGC. In between next frame potential symbols, the AGC is allowed to vary. Next frame potential symbols are analyzed after a transform is calculated to determine if any correspond to a start of a frame.

摘要： A process has been found which increases the efficiency and effectiveness of introducing antimicrobial compounds into complex biofilm matrices through the use of liposome carriers, thereby removing the biofouling in industrial water bearing systems, including piping, heat exchanges, condensers, filtration systems and fluid storage tanks.According to one embodiment of the invention, antimicrobial compound containing liposomes are added to water systems prone to biofouling and biofilm formation. The liposomes, being similar in composition to microbial membranes or cells, are readily incorporated into the existing biofilm. Once the antimicrobial compound containing liposomes become entrained with the biofilm matrix, the decomposition or programmed disintegration of the liposome proceeds. Thereafter the biocidal aqueous core is released to react directly with the biofilm encased microorganisms. Upon the death of the organisms, the polysaccharide/protein matrix decomposes and thereby results in reduced fouling of the water bearing system, resulting in increased heat transfer, increased flux, less deposit of colloidal and particulate solids and dissolved organics on the surface of the microfiltration membrane, thereby reducing the frequency and duration of the membrane cleaning and ultimate replacement.

摘要： In embodiments of frame boundary detection, a data signal that includes a plurality of different synchronization signals is received. Symbol boundaries of orthogonal frequency-division multiplexing (OFDM) symbols are detected in the data signal based on signal characteristics of the OFDM symbols. The characteristics of the OFDM symbols include cyclic shift properties of the OFDM symbols, such as the characteristic that a first portion of an OFDM symbol is the same as a last portion of the OFDM symbol. One or more of the plurality of different synchronization signals in the data signal can be located using the detected symbol boundaries of the OFDM symbols to determine a frame boundary of a data frame in the data signal.
