  • Device for and method of generating pseudo-random sequence uniformly distributed over any range
    Patent number: 7379955
    Abstract: A device for and method of generating an uncorrelated pseudo-random bit sequence by first selecting a user-definable value K. Next, factoring K+1 into m prime factors q1, q2, . . . , qm, where q1, q2, . . . , qm are ordered from smallest value q1 to largest value qm. Next, generating m pseudo-random sequences r1, r2, . . . , rm, where each pseudo-random bit sequence ri is uniformly distributed over a range (0, . . . , qi?1), and where i=1, 2, . . . , m. Finally, generating the uncorrelated pseudo-random sequence as R=r1+q1r2+q1q2r3+ . . . +q1q2 . . . qm?1rm.

  • Method of generating multiple random numbers
    Patent number: 7263540
    Abstract: A device for and method of generating as many as K random bits by generating a first pseudo-random bit, generating a second pseudo-random bit, delaying the second pseudo-random bit a number of times, storing the delayed pseudo-random bits, and combining the first pseudo-random bit with each of the delayed second pseudo-random bits.
