CORRELATION METHOD, MATCHED FILTER AND PORTABLE TERMINAL

摘要

PROBLEM TO BE SOLVED: To solve the problem that a circuit scale is markedly increased when the number of over-samplings is enlarged and to reduce power consumption without markedly increasing the circuit scale. SOLUTION: In this correlation method, registers 1 are cascade-connected by the number of the over-samplings and turned to a register group and input signals and sampling results and code sequences successively outputted from the register group are multiplied in multipliers 2. Output from the multipliers 2 is added in a first adder 3 and the output from the first adder is added by the number of the over-samplings in a moving averaging circuit.
