PURPOSE: A symbol window correlative operation circuit and an address generation circuit therefor are provided to improve transmission quality by enabling to control a data position of symbol data, which is fetched from symbol data stream. CONSTITUTION: An operation circuit with an access timing adaptive control for symbol data comprises memory blocks(11a,11b) that input and store the discrete data sampled at a constant period by sampling, memory blocks for working(12a,12b) that store the intermediate results of the operation or the final computed result, when the operation is executed, and memory blocks for outputting(13a,13b) that also execute address transformation concurrently with transmitting the final computed result. Data-path(16) executes the FFT operation. Multiplexers(14,15) control connections between each memory block and the data-path(16).
