摘要：A radio communications receiver for detecting first and second contemporaneously transmitted radio signals representative of first and second data. An adaptive antenna detects at least one wave front from the first radio signals, and at least one wave front from the second radio signals. A first radio detector which regenerates first data from the first wave front. An interference canceller subtracts the first radio signals, reconstituted from the first data, from the second wave front, dependent on interference from the first wave front to the second wave front. A second data detector regenerates the second data from the second wave front after the subtraction of the first wave front consequent upon the second radio signals. The first and second data are communicated contemporaneously on at least common parts of the radio frequency spectrum. The present invention finds application with wide band code division multiple access signals (W-CDMA) signals as well as time division-code division multiple access signals (TD-CDMA), and time division multiple access signals (TDMA) such as those generated by the GSM system.
