— Feedback of channel state information (CSI) enables a multi-carrier transmitter to optimize the power allocation across sub-channels. We consider a single user feedback scheme ...
Low power radios, such as the CC2420, have been widely popular with recent sensor platforms. This paper explores the potential for energy savings from adding a highpower, high-ban...

—Peak-to-average power ratio (PAR) reduction in OFDM using antenna arrays (MIMO OFDM) is considered. In particular, generalizations of selected mapping (SLM) recently proposed in...
Abstract. Low-power design became crucial with the widespread use of the embedded systems, where a small battery has to last for a long period. The embedded processors need to efï¬...
The size and speed of first-level caches and SRAMs of embedded processors continue to increase in response to demands for higher performance. In power-sensitive devices like PDAs a...
