UCLA electrical engineers have developed a technique that allows polar transmitters to be compatible with wideband systems. The innovation will greatly reduce the power consumption in handheld wireless devices, thereby increasing battery lifetime.
Electrical Engineers at UCLA have developed a discrete-time wideband phase modulation technique that is compatible with polar transmitters. This innovation breaks through previous limitations, making polar architectures compatible with wideband communication systems such as W-CDMA, W-LAN, and WiMAX. Not only is the phase signal bandwidth extended, but common problems of delay mismatch are resolved using this novel discrete-time approach. MORE [2009-048]
