摘要： A computer system may comprise a receiver to perform equalization. The receiver comprises an equalizer. The equalizer may determine locations of a principal tap, a platform noise tap, and a pre-cursor tap in a feedforward path of an equalizer. Also, the equalizer may determine locations of a post-cursor tap, a cross-term tap, and a portable tap in a feedback path of the equalizer. The receiver may align the portable tap in the feedback path with the principal tap in the feedforward path. The platform noise tap may cancel the effect of platform noise on a principal located at the principal tap, thus enabling the computer system to operate effectively in severe platform noise environment. Also, the computer system may operate in statics and portable environment in which platform noise and AGWN may be present.

摘要： Systems, methods, and apparatus for cluster-based optimization of antenna tilts in a wireless network are presented herein. A screening component can receive information indicating wireless conditions of respective wireless access points of a geographical region, select, based on a performance criterion, an access point of the respective wireless access points, and group the access point and an other access point of the respective wireless access points into a representation of a cluster of access points. Further, an optimization component can derive antenna tilt values for respective access points of the cluster of the access points in response to a simulation of an application of the antenna tilt values to the respective access points. Furthermore, an implementation component can direct the antenna tilt values to respective components of the respective access points.

摘要： Briefly, in accordance with one embodiment of the invention, an orthogonal frequency division multiplexing system may provide a dynamically calculated cyclic extension, the length of which may be based at least in part on a delay spread due to an experienced environmental condition. The length of the cyclic extension may be calculated by determining a channel impulse response, and then computing the energy distribution of the channel impulse response. The length of the cyclic extension may then be set according to the energy distribution of the channel impulse response.
