PROBLEM TO BE SOLVED: To provide a random access signal reception circuit adopting a random access system where a training time required for estimating a delay profile and path detection or the like is not deficient and no limit is imposed on an amount of information such as control information to be sent. SOLUTION: A path extract section 14 latches an inverse spread signal outputted from a matched filter section 11 based on a path appearance timing fed from a delay profile timing detection section and provides an output of a transmission symbol of each path. Each of detection sections 15-1-15-n detects a transmission symbol of each path and each of data discrimination sections 16-1-16-n converts the symbol into binary data. When each of random access discrimination sections 19-1-19-n detects correlation between binary data and a random access start, synchronous word, the discrimination sections pass the binary data as control information and when each of the random access discrimination sections 19-1-19-n detects correlation between the binary data with a random access end synchronous word, the discrimination sections stops the output of the control information. |
