Abstract:

A burst processing modem. Implementations may include a receive side including a channelizer adapted to process a plurality of channels and write a plurality of frames to a receive RAM array. A receive frame state machine may be adapted to generate a timing signal using a burst time plan for the plurality of frames. A demodulator may be coupled with the receive RAM array and adapted to read from the receive RAM array only the one or more bursts from the plurality of frames indicated by the timing signal. A transmit side may include a modulator coupled with a transmit frame state machine, with a transmit RAM array, and a combiner bank. The combiner bank may read the modulated plurality of channels from the transmit RAM array and assemble a plurality of frames using a timing signal generated from a burst time plan by the transmit frame state machine.

US Classification:

370464, 370480, 375222, 375219

Abstract:

A burst processing modem and related methods. Implementations of a first method of demodulating bursts from a plurality of channels may include receiving a plurality of channels from a received beam and separating the plurality of channels and storing a plurality of frames in a random access memory (RAM) array with a channelizer where each frame of the plurality of frames includes one or more bursts. The method may include serially reading, using a demodulator in response to receiving a timing signal, a desired burst from a frame stored in the RAM array wherein a burst time plan identifying the desired burst is used by a receive frame state machine to generate the timing signal. The method may include demodulating and decoding the desired burst using a demodulator and a decoder to produce a quantity of packet data, and sending the quantity of packet data to a specified destination.

International Classification:

H04B 1/00
H04B 15/00

US Classification:

455 631, 455 6711, 455522

Abstract:

A method of transmitting telecommunications data comprising modulating a first and a second data signal, transmitting the signals to a remote receiver, the first data signal transmitted from a first terminal and the second data signal transmitted from a second terminal, transmitting, by the remote receiver, the first signal to the second terminal and the second signal to the first terminal, measuring a received signal-to-noise ratio of the first signal received at the second terminal and a received signal-to-noise ratio of the second signal received at the first terminal, and changing a transmit power of at least one of the terminals such that a margin between the signal-to-noise ratio of the first signal and a margin between the signal-to-noise ratio of the second signal is optimized, wherein the margin is equal to a difference between signal-to-noise ratio of a signal received at one terminal and a threshold signal-to-noise ratio.

US Classification:

370328, 370466, 37039553

Abstract:

A multi-channel demodulating system comprising an analog to digital converter (ADC) that samples an input signal and produces a digital signal, a tuning, filtering, and decimation stage coupled to the ADC and configured to select a transponder based on a frequency range of the digital signal and deliver a signal representative of the digital signal to the transponder, and a demodulator coupled to the selected transponder, a decoder, and the circuit stage, the demodulator configured to receive the representative signal from the transponder, the demodulator and decoder configured to separate and process the representative signal to produce a processed signal. The system further comprises a packet de-encapsulation module coupled to the demodulator and decoder configured to de-encapsulate packets of data contained in the processed signal, a switch coupled to the packet de-encapsulation module and a satellite router, the switch configured to transmit the packets of data to the satellite router.

International Classification:

H04B 10/105

US Classification:

455 98

Abstract:

A method of transmitting telecommunications data comprising modulating first and second data signals, selecting transmit powers first and second terminals to achieve a predetermined power equivalent bandwidth (PEB) through an un-attenuated, transmitting the first data signal to the second terminal and the second data signal to the first terminal through a remote receiver, measuring a total received signal-to-noise ratio of the first and second data signals and a total received signal-to-noise ratio received at the second and first terminals, respectively, measuring a signal-power density ratio between the first and second signals, determining a ratio of excess uplink to downlink losses based a rain model parameter and operating frequency, calculating excess uplink and downlink losses relative an optimized, un-attenuated telecommunications channel, and changing a transmit power of a terminal such that the predetermined PEB is maintained when at least one of the signals experiences attenuation.
