Multi-path detecting circuit, system and method

摘要

A matched filter 11 for receiving received data input is connected via a matched filter to a short period delayed profile averaging part 12 and thence to a long period delayed profile averaging part 13. The output of the short period delayed profile averaging part 12 is inputted via a threshold checking part 16 to a finger timing determining part 18. The output of the long period delayed profile averaging part 13 is inputted via a correlation peak retrieving part 17 to a finger timing determining part 18.
