Abstract
A region searcher, a method of driving the same, and a code searcher using the same are disclosed. When a predetermined region is iteratively searched, the energy value corresponding to the same hypothesis location value is stored by using a searcher having divided two buffers, thereby the implementation complexity thereof can be remarkably reduced, without using a simple memory. In addition, in case where the region is iteratively searched in the state of the deteriorated signal-to-noise ratio to find the energy value at one hypothesis location and in case where the region must be iteratively searched because of the restriction which the size of the matched filter can be not increased, the implementation complexity thereof can be remarkably reduced.
