Abstract
A wireless communication system (10) employing quadrature amplitude modulation techniques comprises a system controller (22), at least one radio frequency base transmitter (26), and at least one wireless communication device (35). The system controller (22) generates a downlink call (34) for transmission between the radio frequency base transmitter (26) and the wireless communication device (35). Multiplexing an I-channel bit stream (74) comprised of a first set of calls (70) interleaved together and a Q-channel bit stream (80) comprised of a second set of calls (76) interleaved together generates the downlink call (34). One wireless communication device demultiplexes the downlink call (34) and processes the I-channel bit stream (74). Another wireless communication device demultiplexes the downlink call (34) and processes the Q-channel bit stream (80).
