Abstract: A method is for processing an analog signal coming from a transmission channel. The analog signal may include a useful signal modulated on a sub-set of carriers. The method may include analog-to-digital converting of the analog signal into a digital signal, and synchronization processing the digital signal. The synchronizing may include determining, in a time domain, a limited number of coefficients of a predictive filter from an autoregressive model of the digital signal, and filtering the digital signal in the time domain by a digital finite impulse response filter with coefficients based upon the limited number of coefficients to provide a filtered digital signal. The method may include detecting of an indication allowing a location in the frame structure to be identified, using the filtered digital signal and a reference signal.

Abstract: A method is for processing a channel analog signal coming from a transmission channel. The method may include converting the channel analog signal into a channel digital signal, and detecting a state of the transmission channel based on the channel digital signal to detect whether the transmission channel is, over an interval of time, one or more of linear and time invariant and linear and cyclostationary.

Abstract: A server builds an update file to update software. The server compiles source code of an updated version of the software, generating a binary file of the updated version of the software. Memory locations are mapped to sections of the binary file based on mappings of sections of a binary file of a prior version of the software. Bits of sections of a plurality of sections of the binary file of the prior version are logically combined, bit-by-bit, with bits of corresponding sections of the binary file of the updated version. The logically combining includes: applying an exclusive or operation; or applying an exclusive nor operation. The update file is built based on the mapping of the memory locations and on results of the logical combining.
