Abstract:
A method for reducing interference used in a radio system, the radio system including a plurality of base stations and subscriber terminal equipment, at least one of the plurality of base stations and subscriber terminal equipment being configured to spread a narrowband signal into a broadband signal using a spreading code, the method comprising:receiving one or more different signals having a corresponding spreading code associated therewith using a receiver; forming mutual interference information on the one or more different signals; sending a control command using the receiver based on the mutual interference information, the control command including information about a size of a phase control configured to set a phase setting of the spreading code corresponding to the one or more different signals; changing the phase setting of the spreading code corresponding to the one or more different signals; adjusting the phase of the spreading code corresponding to the one or more different signals using the transmitter based on the control command to diminish mutual interference between the one or more different signals.
