20090034663 | Tone Ordered Discrete Multitone Interleaver - A tone ordered discrete multitone interleaver system and method, including a tone ordered interleaver and deinterleaver, are provided for efficiently communicating data despite noise affecting a Discrete Multitone modulation (DMT) system. The tone ordered discrete multitone interleaver forces interleaving of trellis encoded information by assigning a different number of bits to adjacent tones or adjacent tone pairs. | 02-05-2009 |
20090085873 | Sensory enhancement systems and methods in personal electronic devices - Disclosed are personal electronic devices (PEDs) having a sensory enhancement (SE) system for monitoring environmental conditions and detecting environmental events, for example but not limited to, changes in acoustic, thermal, optical, electromagnetic, chemical, dynamic, wireless, atmospheric, or biometric conditions. The detection of such events can be used to invoke a notification, an alert, a corrective action, or some other action, depending upon the implementation to the PED user or another party. | 04-02-2009 |
20090161792 | System and Method for Adapting to a Change in Constellation Density While Receiving a Signal - One embodiment comprises a transmitter precoder operating on an input signal to produce an output signal for modulation. The output signal is transmitted using a constellation with a constellation density. The transmitter precoder comprises scaler logic, precoder logic and selection logic. The scaler logic scales the input signal to maintain constant power on the input signal independent of the constellation density. The precoder logic precodes the scaled signal to produce a dither signal limited to a range of values. The range is inversely proportional to the constellation density. The selection logic is operable in two states. In the first state, the selection logic combines the scaled signal with the dither signal to produce the output signal. In the second state, the selection provides the scaled signal as the output signal. | 06-25-2009 |
20090262911 | Repeaterless Backhaul - Using the concepts of inverse multiplexing, repeaterless backhaul can be provided on loaded or unloaded loops. Inverse multiplexing can effectively support a large bit rate capacity between the conversion equipment and the CO-side equipment by utilizing a large enough number of potentially low capacity loops. As the distance that the data has to be backhauled increases, the bit rate capacities of the loops generally decrease. However, this decrease in the bit rate capacities of the loops can be compensated for by using inverse multiplexing to gather together enough loops to meet the data rate requirements for backhauling customer data given various service level and contention criteria. | 10-22-2009 |
20090262912 | Splitterless Communication - Distortion caused by a DSL signal can be determined with the DSL signal. The DSL signal and/or the power spectral density (PSD) can be altered to suitably reduce or eliminate the distortion effects, which normally would be reduced by a POTS splitter. As a result of such adjustments to the DSL signal, the POTS band noise is suitably reduced to resolve potential adverse POTS quality issues. In addition, the DSL performance can be improved as well as the undesirable distortion is reduced. Splitterless DSL allows the DSL equipment to be connected to subscriber loops without needing a POTS splitter. This splitterless DSL configuration may be used with conversion equipment utilized to provide indirect DSL service over loaded and/or unloaded loops. In addition, the splitterless DSL configuration also will work with normal DSLAMs. | 10-22-2009 |
