where x0 , x1 , . . ., xn 1 are the n points selected for evaluation of the polynomial. They can be chosen arbitrarily, for example, for simplicity of encoding, or alternatively they can be all the possible integer values that can be represented over the number of bits available. The encoding matrix of Reed Solomon codes has a special form characterized by a geometric progression in each row. Such matrices are named Vandermonde matrices. Decoding Process of RS-Codes. The decoding process consists in reconstructing all the polynomial coef cients a0 , a1 , . . . , ak 1 in a unique way. As is commonly known, for this to be possible, it is suf cient to know the value of the polynomial at exactly k points; that is, receiving k code-words is suf cient. Hence, assuming that the identity (e.g., the sequence number) of the code-words that have arrived to destination is known, the coef cients of the polynomial can be derived at the destination site by solving the following system of equations. yj,1 1 ... = ... ... ... yl,k 1 1 yi,0 1 xi,0 xj,1 ... ... xl,k 1

Under speci ed operating conditions, the Sensor System shall have a probability of detection of 0.XX over a (magnitude) spectral frequency range.

Once the contract is awarded, System Developer SEs are challenged to determine, allocate, and ow down system performance budgets and safety margins requirements derived from higher level requirements such as in the example above. The challenge is analyzing the example above to derive requirements for PRODUCT, SUBSYSTEM, ASSEMBLY, and other levels. Consider the following example.

2 xi,0 2 xj,1

The (name) output shall have a 3s worst-case error of 0.XX for Input Parameter A distributions between 0.000 vdc to 10.000 vdc.

Now let s suppose that an SE s mission is to verify the requirement stated in Example 48.2. For simplicity, let s assume that the sampled end points of Input data are 0.000 vdc and 10.000 vdc with a couple of points in between. We collect data measurements as a function of Input Data and plot them. Panel A of Figure 48.3 might be representative of thess data. Applying statistical methods, we determine the trend line and 3s boundary conditions based on the requirement. Panels C and D of Figure 48.3 could represent these data. Then we superimpose the trend line and 3s boundaries and verify that all system performance data are within the acceptable range indicating the system passed (Panel D).

The preceding discussion focuses on design decisions. Let s explore how system analysts and SEs statistically deal with test data that may be used as an input into SE design decision making or verifying that a System Performance Speci cation (SPS) or item development speci cation requirements has been achieved. Suppose that we conduct a test to measure system or entity performance over a range of input data as shown in Panel A of Figure 48.3. As illustrated, we have a number of data points that have a positive slope. This graphic has two important aspects: 1. Upward sloping trend of data 2. A dispersion of data along the trend line. In this example, if we performed a Least Squares mathematical t of the data, we could establish the slope and intercepts of the trend line using a simple y = mx + b construct. Using the trend line as a central mean for the data set as a function of Input Data (X-axis), we nd that the corresponding Y data points are dispersed about the mean as illustrated in Panel C. Based on the standard deviation of the data set, we could say that there is 0.9973 probability that a given data point lies within the 3s about the mean. Thus, Panel D depicts the results of projecting the 3s lines along the trend line.

Our discussions to this point focus on statistical distributions relative to a speci c capability parameter. The question is: HOW do these errors propagate throughout the system There are several factors that contribute to the error propagation:

The matrix utilized in the decoding process is a submatrix of the encoding matrix and is obtained by selecting the k rows that correspond to the arrived code-words (in the example the ith, jth, . . . , and the lth rows have been selected). The system admits a solution if the matrix is nonsingular. The determinant of the above k k
