As energy availability limits usage time for mobile devices, modern wireless systems implement Power Saving Mechanisms (PSMs). Determining optimal PSM parameters and switch points when applying all PSM mechanisms jointly in the same scenario is a trade-off between power savings and system performance degradation. This work presents an unpublished performance study of the joint operation of Slee...
A dynamic sampling and digital I/Q-mismatch calibration (IQM) in a MB-OFDM UWB baseband transceiver are proposed to reduce ADC power and analog IQM-calibration power. Measured transceiver power consumes 31.2mW, saving at least 43% ADC power and tolerating 10x IQM (2dB gain and 20 degree phase errors) of existing designs to reduce the power and design efforts from analog calibration circuits.
