// The most common case is for the RSA algorithm where the inputs are 2 prime numbers P and Q // and only Q^{-1} mod P is needed (i.e. only the first term of the output array). // // Any of the ouput pointers in the ppeCrtInverses can be NULL and then that result ...
For a check node with adjacent edges, the computation of dc(dc−1) and numerous g( . . . ) functions are performed. However, the forward-backward approach reduces the complexity of the computation to 3(dc−2), in which dc−1 variables are stored....
If f(x)=x^5, then f′(x)= 5x^4According to the power rule for differentiation, the derivative of functions of the form f(x)=x^r is f′(x)=rx^(r−1). If f(x)=1/(x^7), then f′(x)= -7/(x^8)Writing 1/(x^7) as x^(−7), the power rule for differentiation...
Therefore, if the edge information, x0, . . . , xm−1, are all positive, then using (EQ 10) and Property 1 (from above), then all of the newly updated edge information is also greater than or equal to zero (e.g., f(x0, . . . , xm−1)≧0). ...
an embodiment of the present invention. For a check node with dcadjacent edges, the computation of dc(dc−1) and numerous g(.,.) functions are performed. However, the forward-backward approach reduces the complexity of the computation to 3(dc−2), in which dc−1 variables are stored...
In step1013, the decoder305outputs the hard decision (in the case that all parity check equations are satisfied): c^n={0,an≥01,an<0StopifHc^T=0 The above approach is appropriate when non-Gray labeling is utilized. However, when Gray labeling is implemented, ...
invention, and is not intended to represent the only form in which the present invention may be practiced. It is to be understood that the same or equivalent functions may be accomplished by different embodiments that are intended to be encompassed within the spirit and scope of the present ...
The two values, A and B, are also provided to a MUX (Multiplexor) 610, whose selection signal determines the output as being A or B based on the sign bit of the difference between the two values, A−B. For example, only one of A or B is output from the MUX 610. If A is ...
The min**+process and the min**− process are inverse functions of one another. The decoder may also be arranged such that it is operable to perform straightforward min** processing and/or intermediate result sharing min** processing on the min** inputs. In this way, the decoder may ...
