摘要：
A receiver is capable of demodulating both high data rate and low data rate transmissions. An antenna receives the high and low data rate transmissions, as a received signal. An interference canceling device cancels a contribution of at least one shared/common channel from the received signal, producing a first interference canceled signal. A first data detector for detecting data of one of the high or low data rate transmissions by processing the first interference canceled signal. An interference canceling device for canceling the detected data of the one transmissions from the first interference canceled signal, producing a second interference canceled signal. A second data detector for detecting data of an other of the high or low data rate transmissions from the second interference canceled signal.
