Title:
PROCESSING DEVICE AND PROCESSING METHOD
Document Type and Number:
WIPO Patent Application WO/2004/038949
Kind Code:
A1
Abstract:
A processing device and a processing method for suppressing the operation speed of an LSI and reducing the size, weight, and cost of a mobile terminal. Adders (120a-1 to 4) calculate a channel estimation coefficient after updating according to the channel estimation coefficient before the updating, multiplication of a multiplier (110a), GND, a counter value of a 2-bit counter (130) or a selection signal (600). The 2-bit counter (130) generates a 2-bit value by a predetermined clock number and outputs each bit to the adders (120a-2, 3) and a 2-bit counter value to a storage section (140). The storage section (140) outputs the channel estimation coefficient before the updating to the adders (120a-1 to 4) according to the counter value of the 2-bit counter (130) and the selection signal (600) and holds the channel estimation coefficient after the updating in a predetermined storage area according to the counter value of the 2-bit counter (130).
