METHOD FOR GENERATION OF DIGITAL WHITE GAUSSIAN NOISE USING THE WALLACE METHOD Russian patent published in 2020 - IPC H03B29/00 G06F1/02 

FIELD: electrical engineering.

SUBSTANCE: invention relates to electrical engineering and can be used to simulate a communication channel for checking a noise-immune encoding module. In the method it is proposed to generate pseudo-random addresses as follows: p_addr=(start – stride)⊕mask; q_addr=start⊕mask; s_addr=(start + stride)⊕mask; r_addr=(start + stride<<1)⊕mask. Subtraction operation is equivalent to adding operation when using binary-additional code and collectively also takes one cycle. Thus, all four addresses can be obtained in one cycle and transmitted to a memory unit. These addresses are obtained in exact accordance with the Wallace algorithm. It should be noted that subtraction is performed modulo N=1024, i.e. number -1 is equivalent to number 1023. At the same time correlation of output readings is reduced at use of only one matrix A₀ due to use of one of remaining bits from 32-digit reference of generator of uniform random numbers for change of sign of readings p', q', r', s'.

EFFECT: faster operation of a digital white Gaussian noise generator.
