METHOD AND DEVICE FOR PSUEDO-RANDOM PATTERN PHASE DIFFERENCE ARITHMETIC AND STORAGE MEDIUM

摘要

PROBLEM TO BE SOLVED: To obtain a phase difference arithmetic method for PN patterns which can decrease the frequency of operation for obtaining a matrix by calculating the difference between a 1st and a 2nd phase difference calculated as the phase difference between a 1st and a 2nd pseudo-random pattern array. SOLUTION: The 1st and 2nd Pn pattern arrays inputted to a 1st PN pattern input terminal 1a and a 2nd PN pattern input terminal 1b are latched at the same time. The 1st and 2nd PN pattern arrays latched by Pn pattern latch circuits 3a and 3b are transferred to a CPU 6 through a data bus 4 with a transfer request signal inputted from the CPU 6 through a control line 5. The CPU 6 outputs the transfer request signal to the PN pattern latch circuits 3a and 3b through a control line 5 to read in the 1st and 2nd PN patterns which are latched and calculates the phase difference between the 1st and 2nd PN pattern arrays through a phase difference calculating process.
