Abstract (en)

[origin: WO9950973A1] Prior to transmission from the base station, a signal combining method for a CDMA system combines individual frequency channels (f1, f2, f3, f4) into sets of frequency channels such that no two frequency channels in any one set are adjacent in frequency. A dual diversity reception and transmit signal combining system includes two or more signal combiners (34, 36) each coupled to a respective set of frequency channels in which no two frequency channels are adjacent. Two or more duplexors (62, 64) are each coupled to a respective signal combiner. An antenna (38) is connected to each duplexor (62, 64), and two or more splitters (56, 58) are each coupled to a respective duplexor. The respective signal combiners and duplexors can be integrated into single devices.
