摘要： A method and system for transferring data between a sender and a receiver in a packet-based network is disclosed. The method comprises establishing a data channel, establishing a feedback channel, sending data to the receiver over the data channel, sending an acknowledgment to a sender on the feedback channel at a predetermined interval, using the acknowledgment to track data sent successfully and unsuccessfully to the receiver, resending data unsuccessfully sent to the receiver, and self-tuning to optimize throughput based upon the acknowledgement and react to changing network conditions.

摘要： The invention relates to telephone transmission systems in which frequency multiplexing is carried out by digital processes. It consists in substituting to a computation step of an analytical signal a computation step of a much simpler complex signal. The ultimate signal obtained is not compatible with standard multiplexing apparatus, but may nevertheless be transmitted along ordinary channels.

摘要： A carrier frequency system is provided with a transmission band of up to approximately 200 MHz with a small number of partial bands of identical magnitude and kind. These partial bands are translated and cut connected through and vice versa in their entirety into a frequency spectrum within the transmission band of a 60 MHz carrier frequency system of quinary group construction. The partial bands which are cut connected through into the other system are suitable for working with the translators of the other system in the same way as with its own partial bands. The filters required for the system are simple and uncomplicated.

摘要： Multiple adjacent frequency channels employ single sideband AM transmission with re-inserted carrier to afford optimized shared utilization of a common telephone transmission line while adhering to a station carrier frequency standard in which the carriers transmitted from subscribers to the central office reside in a different frequency band than carriers transmitted from the central office to subscribers. The system uses only one stable oscillator per channel, with all other oscillatory signals synchronized thereby. In a preferred embodiment, each subscriber carrier is an integral sub-multiple of the central office carrier for that channel and is obtained by frequency division of the central office carrier. Filtering requirements are minimized by using the phase shift method of SSB generation and reception.

摘要： A speech waveform is converted to a constant amplitude square wave in which the transitions between the amplitude extremes are spaced so as to carry the speech information. The system includes a pair of tuned amplifier circuits which act as high-pass filters having a 6 decibel per octave slope from 0 to 15,000 cycles followed by two stages, each comprised of an amplifier and clipper circuit, for converting the filtered waveform to a square wave. A radio transmitter and receiver having a plurality of separate channels within a conventional single side band transmitter bandwidth and a system for transmitting secure speech information are also disclosed.

摘要： A multichannel, frequency-division multiplex, single-sideband modulation system is realized by using digital filters and product modulators in lieu of conventional analog filters and product modulators. Extremely high multiplication rates resulting from a direct substitution of digital for analog operations are substantially reduced by using multirate digital filters and a combined multichannel implementation of said product modulators and a portion of said multirate digital filters.
