<p>PURPOSE:To provide the digital correlator which decreases the number of required adders to a half as large as before and suppresses an increase in the scale of hardware. CONSTITUTION:The digital correlator is provided with a register 11 which divides and holds an EOR arithmetic result, a selector 3 for the time division of EOR arithmetic results 1 and 2, a register 4 for correlation arithmetic which holds the time-divided EOR arithmetic results of respective blocks, an adder group 5 for finding the correlation values of the respective blocks, and an adder 7 which finds the sum of the correlation values of all the blocks and outputs the total correlation value.</p> |
