摘要： Disclosed are various embodiments providing adaptive path selection for interference cancellation for wireless communication devices. Signal strength metrics are obtained for each of multiple signal paths.

摘要： A “Book of Business” (or Book) is a set of business domain data of one or more book types. This set of data is identified by a “driving condition” or quality. A driving condition typically arises from a business practice, and may be further qualified by local conditions. Accordingly, data may be organized based on local activities or conditions that may not be explicitly stored in a database. In one embodiment, a method for querying the database includes identifying data in a database. The data is organized into one or more segments. A book of business associated with a segment in the one or more segments is then generated. The book of business includes a set of references to the data organized into the segment. A query plan may be determined based on the book of business. A set of results may then be generated based on the query plan.

摘要： Aspects of a method and system for a programmable interference suppression module may include receiving a communication signal comprising one or more desired signal, and one or more undesired signals. The communication signal may be utilized to generate estimated channel state information. The estimated channel state information may be formatted for use in interference suppression. A reduced interference signal may be generated from a delayed version of said communications signal and the estimated channel state information, wherein the one or more undesired signals may be attenuated. The reduced interference signal may be formatted for post-processing. The desired signals may comprise WCDMA and/or HSDPA signals, and the undesired signals may be inter-cell and/or intra-cell interference. Further processing may comprise HSDPA processing and/or RAKE finger processing. The communication signal may be a Universal Mobile Telecommunication System (UMTS) compliant signal.
