摘要： A method performed on-board by a satellite for processing a signal received from a terminal during a current time interval, includes receiving, during the current time interval, a main signal containing a message from a terminal, each message having a priority level; sampling the main signal to obtain samples; storing the obtained samples into the satellite memory; first demodulating the messages corresponding to the current time interval contained in the samples stored in memory; when the satellite is in the range of a ground station, transmitting to the ground station the content of the memory. The first demodulating includes, for each message of the messages contained in the samples and by priority order: demodulating and decoding the message; forwarding, using direct link or inter-satellite-link, the demodulated message to a ground station; estimating the number of remaining non-demodulated messages in the samples stored in the memory.

摘要： A method for recovering content such as an HTML page corresponding to a URL address by a client device, includes, based on a URL address corresponding to the content, the client device checks for the presence of the content of the URL address in a cache memory of the client device; in absence of the content of the URL address in the cache memory, the client device creates a short message including the URL address; the message is transmitted to a server device by a one-way transmission protocol without establishment of a connection; the server device downloads the content corresponding to the URL address from the internet network; the content is transmitted to the client device by the server device via a one-way protocol with coding without acknowledgement; the content is received by the client device; and the content is recovered and stored by the client device in the cache memory.

摘要： A radio communications method includes carrying out, by a transmitter, transmission operations that include generating digital transmission signals carrying symbols to be transmitted and having a predefined time length; and transmitting a radio frequency signal carrying, in successive, non-overlapped time frames or slots having the predefined time length, the digital transmission signals generated. The method further includes carrying out, by a receiver, reception operations that include receiving the radio frequency signal transmitted by the transmitter; processing the received radio frequency signal to obtain a corresponding digital incoming signal; applying an oversampling operation to the digital incoming signal thereby obtaining an oversampled digital incoming signal; detecting successive, non-overlapped time frames/slots with the predefined time length in the oversampled digital incoming signal; and, for each detected time frame/slot, estimating respective symbols carried by the oversampled digital incoming signal in the time frame/slot with a predefined reception matrix incorporating a predefined Kalman filter.
