Embodiment Construction

[0019] The present invention relates to systems and methods for detecting and / or decoding information, and more particularly, to systems and methods for reducing noise in detecting and / or decoding information.

[0020] Various embodiments of the present invention provide data processing circuits that reduce or eliminate the effects of read and / or write noise associated with transferred data sets. In some embodiments of the invention, said noise reduction is selectively utilized. In such cases, the noise reduction may involve some degree of latency. By selectively enabling noise reduction, the delay only occurs when necessary. In some embodiments of the invention, said noise reduction is provided by multiply receiving a given data set and averaging multiple reads. This averaging process helps reduce data-independent noise that may have been introduced during the transfer of the data set. The averaged data set is then provided for data detection, wherein the noise reduction i...

Abstract

Various embodiments of the present invention provide systems and methods for data processing. For example, some embodiments of the present invention provide noise reduced data processing circuits. Such circuits include a selector circuit, a sample set averaging circuit, and a data detection circuit. The selector circuit provides either a new sample set or an averaged sample set as a sample output based on a select control signal. The sample set averaging circuit receives the new sample set and provides the averaged sample set. The averaged sample set is based upon two or more instances of the new sample set. The data detection circuit receives the sample output, and performs a data detection algorithm on the sample output and provides the select control signal and a data output.

Description

[0001] Cross References to Related Applications [0002] This application claims priority to US Patent Application (Non-Provisional Patent Application) No. 61 / 116,389, filed November 20, 2008, by Yang et al., entitled "Systems and Methods for Noise Reduced Data Detection." The above patent application is hereby incorporated by reference in its entirety for all purposes. technical field [0003] The present invention relates to systems and methods for detecting and / or decoding information, and more particularly, to systems and methods for reducing noise in detecting and / or decoding information. Background technique [0004] A variety of data transfer systems have been developed, including storage systems, cellular telephone systems, and radio transmission systems. In each of the systems described above, data is transmitted from a sender to a receiver via some medium. For example, in a storage system, data is sent from a sender (ie, a write function) to a receiver (ie, a rea...
