| 20090175234 | Enhanced Sub-Frame-Based-Framing for Wireless Communications - A method of performing wireless communications. The method comprises, at a transmitting station, encoding a plurality of symbols into a frame. The method further comprises, from the transmitting station, transmitting the frame via a wireless communication to a receiving station. The frame comprises a plurality of sub-frames, wherein a first sub-frame in the plurality of sub-frames consists of a first number of symbols and a second sub-frame in the plurality of sub-frames consists of a second number of symbols. Finally, the first number differs from the second number. | 07-09-2009 |
| 20090274200 | System and Method for Time Domain Interpolation of Signals for Channel Estimation - A system and method for time domain interpolation of signals for channel estimation. A method for computing channel estimates comprises storing symbols in a buffer, using time domain interpolation (TDI) for a first time to compute channel estimates for a set of sub-carriers of a symbol. The channel estimates are computed from the symbol and a first number of required symbols in the buffer. The method also comprises using TDI for a second time to compute channel estimates for the set of sub-carriers of a symbol. The channel estimates are computed from the symbol, a second number of required symbols in the buffer, and a buffered symbol used as a missing required symbol if the missing required symbol is not in the buffer. | 11-05-2009 |
| 20110064242 | Method and System for Interference Suppression Using Blind Source Separation - A method of interference suppression is provided that includes receiving a first audio signal from a first audio capture device and a second audio signal from a second audio capture device wherein the first audio signal includes a first combination of desired audio content and interference and the second audio signal includes a second combination of the desired audio content and the interference, performing blind source separation using the first audio signal and the second audio signal to generate an output interference signal and an output audio signal including the desired audio content with the interference suppressed, estimating interference remaining in the output audio signal using the output interference signal, and subtracting the estimated interference from the output audio signal to generate a final output audio signal with the interference further suppressed. | 03-17-2011 |
| 20110123019 | METHOD AND APPARATUS FOR CROSS-TALK RESISTANT ADAPTIVE NOISE CANCELLER - A method and apparatus for cross-talk resistant adaptive noise cancellation. The method includes retrieving, via the processor, a primary signal and a reference signal, filtering the primary signal utilizing a filter H | 05-26-2011 |
