ABSTRACT:
In a communication apparatus which transmits parameters corresponding to a reception environment to a transmitting apparatus which switches the transmission rate based on the reception environment, reception quality calculated in the past is saved as a first reception quality, and past CPICH symbols used in calculating this first reception quality are saved. Channel compensation of the saved past CPICH symbols is performed using a current channel estimation value, and the channel-compensated CPICH symbols are used to calculate a second reception quality; the difference between this second reception quality and the first reception quality is used as a reception quality correction value to correct reception quality.
