This filter is often a square-root raised cosine filter, but you can also use a Butterworth, Bessel, Chebyshev type 1 or 2, elliptic, or more general FIR or IIR filter.

For example, to consider only the first and last elements of a length-six receiver frame, set the Selected samples from frame parameter to [1 6]. This section mentions some of the tools you can use to create error rate plots, modify them to suit your needs, and do curve fitting on error rate data. In either the bit- or symbol-counting case, the error rate is the number of errors divided by the total number (of bits or symbols) transmitted.Note: To ensure an accurate error rate, Berawgn Matlab For an example of how the BER Figure window looks, see Example: Using the Theoretical Tab in BERTool.Interaction Among BERTool Components.The components of BERTool act as one integrated tool.

Some parameters are visible and active only when other parameters have specific values. Each entry of individual corresponds to a comparison between a pair of elements of x and y, and specifies the number of bits by which the elements in the pair differ.Examplescollapse If EbNo is a vector, berub is a vector of the same size, whose elements correspond to the different Eb/N0 levels. news An error is a discrepancy between corresponding points in the two sets of data.Of the two sets of data, typically one represents messages entering a transmitter and the other represents recovered

The receive delay persists throughout the simulation.The Computation delay parameter represents the number of samples the block ignores at the beginning of the comparison.If you do not know the receive delay The three subbullets above are still valid for this mode, except that if Rx is a scalar, then the phrase "Rx frame" above refers to the vector expansion of Rx.Note This Acknowledgments Trademarks Patents Terms of Use United States Patents Trademarks Privacy Policy Preventing Piracy © 1994-2016 The MathWorks, Inc.
