Power Reduction with Dynamic Sampling and All-Digital I/Q-Mismatch Calibration for A MB-OFDM UWB Baseband Transceiver
نویسندگان
چکیده
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.

Simulation of Interference Effects from UWB Sources on a Narrowband Digital Transmission System
−This paper studies the interference effects from 4 types of ultra wide band (UWB) sources on a narrowband π/4-shift differential quadrature phase keying (DQPSK) transmission system by simulation. The culprit UWB sources were: multi-band orthogonal frequency-division multiple-access (MB-OFDM), direct-sequence code-division multiple-access (DS-CDMA), DS spread spectrum UWB (DS-SS UWB), and addit...

Orthogonal frequency division multiplexing (OFDM) has been widely recommended to the most promising baseband modulation and multiplexing technology for 3G and 4G communication systems because of its spectral efficiency and robustness against frequency selective fading channel. Furthermore, direct conversion based RF transceiver has had more advantages in aspects of power consumption, area and c...
متن کاملNew I/Q imbalance modeling and compensation in OFDM systems with frequency offset
In this paper, a new model and compensation scheme of quadrature imbalance in analog I/Q OFDM transceivers is presented. Classically, the effect of I/Q imbalance is modeled by a cross-talk between pairs of symmetrical OFDM sub-carriers. We show that this model is not valid when the carrier frequency offset is compensated after the source of I/Q mismatch. Assuming a perfect digital compensation ...
