Abstract: A method for compressing a short message includes receiving a short message that includes a plurality of text strings for compression, dividing the short message into one or more sub-blocks, where a number of text strings in each of the one or more sub-blocks is less than or equal to a predetermined number. The method also includes compressing each of the one or more sub-blocks by identifying a type of a first text string, identifying a code representing the type, determining whether the first text string exists in a library, upon determining that the first text string exists in the library, determining an index corresponding to the first text string, extracting a predetermined number of least significant digits of the index, and replacing the first text string in that sub-block with the code and the extracted predetermined number of least significant digits of the index.

Abstract: Systems (400) and methods for reducing a number of cyclostationary features in a transmitted signal. The methods comprise: obtaining by a transmitter a discrete-time IF signal comprising a sequence of samples all having a same sample duration; performing operations by a sub-sample dithering processing device of the transmitter to modify a sample timing of the discrete-time IF signal by decreasing or increasing a duration of at least one first sample of the sequence using a digital signal processing technique in a digital domain; converting the discrete-time IF signal to an RF signal; and transmitting the RF signal having a reduced number of cyclo stationary features.

The method comprising: receiving, by a receiver, the transmitted RF signal; converting, by the receiver, the transmitted RF signal into a discrete-time IF signal comprising a sequence of samples, where at least a first sample of said samples has a first sample duration different than a second sample duration of at least a second sample of said samples; and performing operations by a sub-sample dither removal device of the receiver to modify a sample timing of the discrete-time IF signal by decreasing or increasing the first sample duration of the first sample using a digital signal processing technique in a digital domain.

Abstract: The digital video communications device includes a scalable video coding (SVC) controller including an encoder and associated block equalizer. The encoder is configured to receive digital video, and encode received digital video into a plurality of related streams including a base layer having a first modulation type, and scaled enhancement layers having different modulation types. The block equalizer is configured to generate a waveform by sequentially interleaving the plurality of related streams with equalizer probes. The digital video transmission approach allows the receiver to automatically provide the best video quality that the channel will support without negotiation with the transmitter.

Abstract: Systems (100) and methods (200) for controlling video stream distribution in an ad hoc network. A first network node (116 or 120) receives a first video stream (108) having a Scalable Video Codec format and a first Data Transfer Rate (“DTR”). The first network node resides between a video source device (102/106) and a video destination device (124, 128 or 132). The first network node then determines a second DTR for the first video stream based on conditions of communications links between the first network node and at least one second network node (118, 120, 126 or 130) downstream from the first network node. The first video stream is transferred from the first network node to the second network node at the second DTR which was previously determined, whereby any link quality impediments within the ad hoc network are resolved locally at the first network node.
