Using TF-IDF to Determine Word Relevance in Document Queries : In this paper, we examine the results of applying Term Frequency Inverse Document Frequency (TF-IDF) to determine what words in a corpus of documents might be more favorable to use in a query. As the term implies, TF-IDF calculates values for each word in a document through an inverse proportion of the frequency of the word in a particular document to the percentage of documents the word appears in. Words with high TF-IDF numbers imply a strong relationship with the document they appear in, suggesting that if that word were to appear in a query, the document could be of interest to the user. We provide evidence that this simple algorithm efficiently categorizes relevant words that can enhance query retri

The is a fully functional GPS SDR. It can accept real data or simulate its own data. It performs correlation, signal parameters discrimination, and loop filtering both code and carrier with the option of carrier loop aiding of the code loop. There are many support functions such as the numerically controlled oscillator, coarse acquisition code generator that are in the archive. This does not include the acquisition engine, just the channel tracking state machine. The also outputs carrier phase measurements and modulo 1ms pseudorange.
