1. In a wireless communication system having a system controller, a radio frequency base transmitter, and at least one wireless communication device, a method employing quadrature amplitude modulation for communicating a downlink call between the radio frequency base transmitter and the wireless communication device, the method comprising:

  • interleaving a first set of calls, and generating an I-channel bit stream comprised of the interleaved first set of calls;

    interleaving a second set of calls, and generating a Q-channel bit stream comprised of the interleaved second set of calls;

    generating the downlink call by modulating the I-channel bit stream onto an in-phase carrier component of the downlink call and modulating the Q-channel bit stream onto a quadrature phase carrier component of the downlink call.
