Title: Reception radio search method and broadcasting receiver
Inventor: KYOJO HIROYUKI
IPC: H04B1/16
Filed: 2000-12-15
Abstract: PROBLEM TO BE SOLVED: To solve the problem that it takes a long time to perform the frequency search operation of DAB(digital audio broadcasting) since it is not until demodulation processing is performed on all frequencies in a frequency band that whether or not any DAB signal is present is judged. SOLUTION: A control unit 9A checks whether or not a null symbol is detected 5 times in a row at the time of searching DAB broadcasting, and when any null symbol is not detected even one time, it is judged that any DAB signal is not present, and the next frequency is searched. As long as the null symbol is detected 5 times in a row, it is judged that the DAB signal is present, and the DAB signal is fetched in a DAB signal demodulating part 5 so as to be demodulated. Thus, it is possible to reduce the search time to the half or less of the conventional manner by making it unnecessary to perform the demodulation processing on all the frequencies.
