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