1. A method for providing data for automatically estimating channel performance if different parameters of a Reed-Solomon (RS) code are used in a communication system while transmission is occurring in the communication system without changing the current Reed-Solomon (RS) code parameters comprising the steps of:

  • a. receiving an input signal from the channel;

    b. processing the input signal in a receiver in the communication system, the receiver having a Reed Solomon decoder having an output of RS symbols;

    c. choosing a virtual RS block code size;

    d. determining a RS number of errors data by determining how many RS symbols in a sequence of RS symbols the size of the virtual RS block code size are erred RS symbols;

    e. determining a RS sequence of errors data by determining how many occurrences there are of erred RS symbols that occur sequentially in the sample and the number of sequential erred RS symbols in each occurrence; and

    f. outputting the RS number of errors data and RS sequence of errors data.
