In a code division switch in a satellite communication system each of a plurality of uplink CDMA modulated RF beams, each including a plurality of uplink traffic channels, are down converted to IF and overspread with a new orthogonal code having a spreading rate N times that of the spreading code of the uplink CDMA modulated RF beam. All of the overspread beams are combined into a single combined IF stream. The individual traffic channels are extracted from the combined IF stream by de-overspreading the stream with orthogonal codes and despreading with beam and traffic channel specific orthogonal codes. All traffic channels are respread with downlink beam codes and downlink orthogonal traffic channel codes and joined onto selected ones of downlink CDMA modulated IF beams having common destinations with the included traffic channels. Downlink CDMA modulated IF beams are up converted to RF frequency and transmitted to selected destinations.
