Voltage overscaling for power reduction in RF systems has been limited by the need to maintain sufficient overscaling guard bands to ensure that minimum signal quality requirements of the end to end communication link are met. In this paper, we propose error control mechanisms at the symbol (probabilistic symbol remapping) and bit levels (code based correction and feedback) that allow more aggressive...
Modern wireless communication systems are designed for worst-case channel noise and interference conditions. This results in circuits that over-perform and consume more power than necessary most of the time when channel conditions are not worst-case. In this paper, we propose a power savings methodology that allows "graceful degradation" of baseband system performance when channel conditions...
Modern wireless transceiver systems are designed to operate under worst case channel operating conditions (interference, adjacent channel power, multi-path effects). This results in very tight performance specifications for the front- end RF circuit components. In this paper, we develop an adaptive power management strategy for RF systems that delivers just enough power (and performance) to the RF...
Bit error rate (BER) is a key specification that characterizes the performance of a communication receiver. In digital radio applications, running BER tests during production is highly prohibitive in terms of test cost due to the prolonged testing time required for applying RF modulated digital data-frames (each containing pseudo-random bit patterns) to the receiver and capturing the response digital...
