Receiver and channel estimation method

A receiver, comprising:

• an equalizer circuit configured to process a first data signal according to a control signal, in order to generate a second data signal;
• a radio frequency interference cancellation circuitry configured to detect a radio frequency interference signal according to the second data signal to generate radio frequency interference information, and to output a correction signal according to the radio frequency interference information, in order to correct the second data signal;
• and
• a channel estimation circuitry configured to analyze a first power of a first signal component and a second power of a second signal component in each of a plurality of sets of signal components in the second data signal, compare the first power of the first signal component in each of the plurality of sets of signal components with each other, and compare the second power of the second signal component in each of the plurality of sets of signal components with each other, in order to utilize a power ratio of one of the plurality of sets of signal components to generate the control signal.
