ABSTRACT:
A method and apparatus for combining and separating groups of signals starts by a transmitter (500) receiving a number of CDMA-encoded signals from data sources (510). The CDMA-encoded signals are sorted (502) based on their intended destinations. Those CDMA-encoded signals which are intended for a common destination are multiplexed (504) together into a group. The group is further CDMA encoded (506) using a group code and the encoded group is transmitted (508) to an intermediate transceiver (600) or a destination transceiver (700). The intermediate or destination transceiver decodes (604, 704) the group using the appropriate group code and routes the resulting group of signals accordingly.
