20100046958 | System and Method For Reducing Memory Requirements For Electrical Domain Compensation of Intra-Channel Nonlinearity In An Optical Communications System - A digital filter is provided for processing an electrical input signal to be conveyed through an optical communications system. The processing generates a predistorted electrical signal using a compensation function that substantially mitigates for intra-channel non-linearity imparted to the communications signal by the optical communications system. The digital filter has a memory having a limited size storing a reduced data set used for approximating an original, unreduced data set used to implement the compensation function. The reduced data set is used for the digital filter to apply the compensation function to mitigate the intra-channel non-linearity over longer transmission distances of the optical communications system than would be possible without the use of the reduced data set. | 02-25-2010 |
20120148262 | SYSTEM AND METHOD FOR REDUCING MEMORY REQUIREMENTS FOR ELECTRICAL DOMAIN COMPENSATION OF INTRA-CHANNEL NONLINEARITY IN AN OPTICAL COMMUNICATIONS SYSTEM - A digital filter processes an input signal to be conveyed through an optical communications system. The processing generates a predistorted signal using a compensation function that mitigates impairments of the optical communications system. The input signal has a sample period of T, while the predistorted signal has a sample period of T/2. The digital filter has a first branch including a respective first T-spaced filter for processing the input signal using the compensation function to generate a corresponding first output signal comprising nT/2 samples with n odd. A second branch includes a respective second T-spaced filter for processing the input signal with a delay of T relative to the first branch using the compensation function to generate a corresponding second output signal comprising nT/2 samples with n even.

A cognitive radio base station broadcasts the low power reference wideband chirp signal with bandwidth covering the sensed spectrum. At the receiver, spectral resolution in the presence of white noise is achieved by cross-correlating the chirp signal with a locally generated copy of itself (i.e., matched filtering). A Fast Fourier Transform (FFT) is applied to the output of this matched filtering. The FFT output is fed to a decision circuitry, where a threshold value is set to decide the minimum amplitude of utilized frequencies. This process eases sensing computational complexity and improves the quality of sensing, thereby offering enhanced cognition at the cognitive radio receiver. | 07-04-2013 |

20090235358 | SYSTEMS AND METHODS FOR ATTACHING A VIRTUAL MACHINE VIRTUAL HARD DISK TO A HOST MACHINE - Various embodiments of the present invention are directed to systems and methods for “attaching” a virtual hard drive to the physical computer hardware by implementing a specialized disk controller driver for the host operating system that is recognized by the host operating system as a disk controller driver but which in fact also emulates the virtual hard disk it is “attached” to. When the host operating system sends requests to read and write sectors from the virtual hard drive, the specialized driver (the “virtual hard drive controller driver”) directly accesses and manipulates the back-end file mentioned above. Thus the virtual disk is “attached” and recognizable by the host operating system and can be manipulated thereby (and applications executing thereon). | 09-17-2009 |
