A checksum of a message is a modular arithmetic sum of message code words of a fixed word length (e.g., byte values). The sum may be negated by means of a ones'-complement operation prior to transmission to detect unintentional all-zero messages.
Turbo coding is an iterated soft-decoding scheme that combines two or more relatively simple convolutional codes and an interleaver to produce a block code that can perform to within a fraction of a decibel of the Shannon limit.
For an optimized detector for digital signals the priority is not to reconstruct the transmitter signal, but it should do a best estimation of the transmitted data with the least possible number of errors. The receiver emulates the distorted channel. All possible transmitted data streams are fed into this distorted channel model.

Since the source is only 4 bits then there are only 16 possible transmitted words. Included is the eight-bit value if an extra parity bit is used (see Hamming(7,4) code with an additional parity bit).
The visitor's RSS feed activity can then be tracked accurately using standard web analytics applications. The problem with this method is that if the feed is syndicated by a search engine for instance then this will defeat the purpose of the unique URLs as many people could potentially view the RSS feed via a single URL.
Windows RSS Platform does not support feeds that reference a DTD. [1] Although feed reading view can be disabled, custom stylesheets cannot be applied to feeds in Internet Explorer. Internet Explorer uses an internal stylesheet for feed reading view. [2] Prior to IE8, the RSS platform did not support authentication/storing credentials. [3]
RSS feed data is presented to users using software called a news aggregator and the passing of content is called web syndication. Users subscribe to feeds either by entering a feed's URI into the reader or by clicking on the browser's feed icon. The RSS reader checks the user's feeds regularly for new information and can automatically download ...
