Abstract
A method for reducing interference and a radio system where a signal spreadcoded by digital pseudo noise is used for communication are provided. As the delay distribution of the signals of subscriber terminal equipment at base stations is great and thus the mutual interference of the signals may also be great, the base station adjusts the phase of the spreading codes of the subscriber terminal equipment so as to reduce interference. The method and the radio system enable high data rates and reduce the calculation required for interference correction.
