How is channel state information calculated?

Channel state information (CSI) is basically calculated using the pilot signals used during transmission and compared with the received pilot signals, while the SNR reflects the strength of the transmitted signal in respect of the channel noise.

What is CSI in MIMO?

In a MIMO system, a transmitter with perfect knowledge of the underlying channel state information (CSI) can achieve a higher channel capacity compared to transmission without CSI.

What is imperfect channel state information?

Imperfect channel state information (I-CSI) and imperfect transceiver hardware often happen in wireless communication systems due to the time-varying and random characteristics of both wireless channels and hardware components.
