1. A receiver capable of demodulating both high data rate and low data rate transmissions, the receiver comprising:

  • an antenna for receiving the high and low data rate transmissions, as a received signal;

    an interference canceling device for canceling 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; and

    a second data detector for detecting data of an other of the high or low data rate transmissions from the second interference canceled signal.
