Reduced-Complexity Joint Baseband Compensation of Phase Noise and I/Q Imbalance for MIMO-OFDM Systems
The maximum likelihood estimate of the impulse response of a frequency-selective channel in the presence of phase noise and I/Q imbalance is derived. The complexity of the joint es...

Analog parallelism in ring-based VCOs
The performance advantages in parallel ring-based VCOs are explored. When the number of VCOs is doubled, the parallel VCOs enhance phase noise by 3dB, and the within-chip process-...
