Abstract
The invention relates to a frequency hopping method and a base station including, at the receiver end, a number of baseband processing units and broadband receiver units, which form RF sub-bands and receive frequency hopping signals according to a frequency hopping sequence from the RF sub-bands they have formed. The base station includes, at the receiver end, a switching device and channelling unit, which receive baseband signals from an intermediate band and each of which is connected to a receiver unit forming a particular RF sub-band. The switching device selects, according to the frequency hopping sequence, the channelling unit whose baseband output provides the baseband signal which is connected to the baseband processing unit. The channelling unit places the baseband signals to its baseband output according to the frequency hopping sequence.
