Abstract: PURPOSE:To make relatively easy to generate the pseudonoises bearing desired correlations of time and space, by combining white noise generators with a filter group with prescribed characteristics. CONSTITUTION:Random numbers written in memory RAM and sent from random- number generator RNG are separated into four sequences and on the basis of an address signal generated by control part CU, respective sequences are processed by filters F1-F4 by summing up the product of a random number read out of memory RAM and a filter coefficient read out of memory ROM obtained by multiplier MPY, by accumulator ACC. Then, the result is stored in the other part of memory RAM. Next, output signals filters F1-F2 are similarly processed by F11...F41 and their results are added and sent to DA converter DA1, whose output is outputted from output terminal I1. Similarly, output signals are sent out from output terminals I2- I4. Thus, the pseudonoises bearing a random space correlation can be generated for four receivers.
