摘要： A signal processing method for a MIMO system comprises the steps of: arranging a plurality of frequency domain MIMO data streams into a plurality of groups, wherein each group comprises at least a frequency domain MIMO data stream; partitioning sub-carriers of each of the plurality of frequency domain MIMO data streams into a plurality of sub-channels; performing phase rotation for the plurality of frequency domain MIMO data streams, wherein the phases of the sub-carriers in a sub-channel are rotated the same amount, and different phase rotations are performed on different groups of the plurality of frequency domain MIMO data streams; transforming the plurality of frequency domain MIMO data streams into a plurality of time domain MIMO data streams; and performing CSD for the plurality of time domain MIMO data streams if each group comprises more than one frequency domain MIMO data stream, wherein the amount of CSD is different for each time domain MIMO data stream in a group.

摘要： A method for calibrating an analog circuit component comprises the steps of: generating a first signal with a baseband frequency; generating a second signal by processing the first signal via the analog component to be calibrated; generating a third signal by processing the second signal via a power amplifier, wherein the power amplifier operates in a nonlinear region; generating a fourth signal by processing the third signal via a low-pass filter; and defining the adjustment for the In-phase-Quadrature-phase imbalance (IQ imbalance) of the analog component and then re-executing the step of generating the first signal, if the fourth signal shows an IQ imbalance mismatch.
