ABSTRACT:
A method is provided for increasing data throughput in a wireless telecommunications environment. The method includes the following steps: mapping a discrete bit sequence associated with a subscriber to an in-phase component and a quadrature component, the in-phase component and the quadrature component defining modulation of a radio frequency signal in phase and magnitude; and encoding the in-phase component and the quadrature component with a multiple access sequence associated with the subscriber.
