Cellular system, mobile portable apparatus, base station apparatus, optimum path detecting method, and apparatus thereof

摘要

A cellular system using code divisional multiple access (CDMA) system is disclosed, that comprises a plurality of finger circuits, and a search engine portion having a reception level measuring portion for detecting reception levels from reception signals and comparing the reception levels with a predetermined threshold value. An inner memory stores correlation signals received from the plurality of inversely spreading portions, and a reception path timing generating portion detects the reception paths from the output signals of the inner memory and generates a path timing. Whenever the reception level falls under the threshold. The present correlation peak is discarded and the memory output the correlation peak of the previous frame.
