摘要： A receiver of a digital signal equipped with an N-state weighted-decision trellis Viterbi decoder, the signal received including a series of symbols, is provided. The receiver comprises a programmable logic circuit that includes a source memory A and a destination memory B each comprising N rows and M+L columns respectively allocated to M fixed fields for describing the trellis, and to L variable fields, and an operator able to calculate the variable fields of a memory as a function of the fixed fields of the said memory, of the symbols received and of the variable fields of the other memory and able to reverse the role of the source memory and destination memory.

摘要： A processor system and communications processor between a plurality of sub-components is described. To each sub-component of equipment is associated at least one logical channel that is associated with at least one physical channel. Each sub-component addressing only the logical channels that it is associated with, and the various physical channels being time multiplexed on an internal communications bus (BCI). The system has particular application to systems of radio-communication or of embarked navigation.

摘要： The field of the invention is that of the reception of a radionavigation signal originating from a satellite positioning system such as the GPS system. The present invention concerns a method for calculating correlations between a first sequence and a second sequence, said first sequence and said second sequence having a duration DCode, the first sequence being extracted from a digital signal comprising a code, said code comprising elementary time divisions, called chips, of mean duration Dchip, said chips being synchronized with pulses delivered by an NCO oscillator at the mean frequency 2/Dchip, the second sequence resulting from a sampling at a frequency Fe of an analog signal, the frequency Fe being greater than 2/Dchip. According to the invention, the method comprises a step of aggregating samples of the second sequence, over consecutive integration intervals of duration equal on average to Dchip/2, starting at each pulse of the NCO oscillator, so as to determine results of elementary aggregates.
