Energy Scalable Radio Design

Smart energy management is indispensable in modern radios. This book describes and applies an energy-driven design strategy to the design of an energy-efficient, highly scalable, pulsed UWB receiver, suitable for low data rate communication and sub-cm ranging.

Smart energy management, both at design time and at run time, is indispensable in modern radios. It requires a careful trade-off between the system's performance, and its power consumption. Moreover, the design has to be dynamically reconfigurable to optimally balance these parameters at run time, depending on the current operating conditions.

Energy Scalable Radio Design describes and applies an energy-driven design strategy to the design of an energy-efficient, highly scalable, pulsed UWB receiver, suitable for low data rate communication and sub-cm ranging. This book meticulously covers the different design steps and the adopted optimizations: System level air interface selection, architectural/algorithmic design space exploration, algorithmic refinement (acquisition, synchronization and ranging algorithms) and circuit level (RTL) implementation based on the FLEXmodule-concept. Measurement results demonstrate the effectiveness and necessity of the energy-driven design strategy.

Covers energy-driven design strategy, including novel "FLEXmodule" implementation concept Explains need for run-time reconfigurability and how to introduce it at design time Describes complete system-to-(digital)circuit design of an IR-UWB based radio Discusses algorithms and strategies for sub-cm ranging and fast data acquisition All results are validated on actual silicon implemented designs
