Method and system for measuring receiver mixer IQ mismatch |
摘要 |
Aspects for measuring receiver mixer IQ mismatch in a transceiver are described. The measuring includes providing a training signal for a receiver mixer, the training signal having periodic, uncorrelated I and Q signals. A phase mismatch in the receiver mixer is determined from IQ correlation over a unit period. A gain mismatch in the receiver mixer is determined from a power estimate of both I and Q signal for the unit period.
