Abstract:
1. A receiver comprising: a first selection filter comprising a first pass band substantially in the center of a carrier configured to filter an input signal and to output a filtered signal; a second selection filter comprising a second pass band narrower than the first pass band substantially at the center of the carrier configured to filter an input signal and to output a filtered signal; a first switching circuit configured to switch a first output signal between an output signal of the first selection filter and an output signal of the second selection filter; a first tuner configured to frequency-convert a signal from a first antenna into a first signal, to output the first signal to the first selection filter and the second selection filter, to process the first output signal from the first switching circuit into a second signal, and to output the second signal; a first analog-to-digital converter configured to convert the second signal from analog to digital and to output the converted second signal; a third selection filter comprising a third pass band narrower than the second pass band substantially at the center of the carrier configured to filter an output signal of the first analog-to-digital converter, and to output a filtered signal; a delay compensator configured to output the output signal of the third selection filter delayed by a predetermined delay time; a second switching circuit configured to switch a second output signal between the output signal of the third selection filter and the signal output from the delay compensator; a fourth selection filter comprising a same pass band as the second pass band configured to filter an input signal and to output a filtered signal; a second tuner configured to frequency-convert a signal from a second antenna into a third signal, to output the third signal to the fourth selection filter, to process a signal from the fourth selection filter into a fourth signal and to output the fourth signal; a second analog-to-digital converter configured to convert the fourth signal from analog to digital and to output the converted fourth signal; a fifth selection filter comprising a same pass band as the third pass band configured to filter an output signal of the second analog-to-digital converter and to output a filtered signal; and a multipath equalizer configured to receive output signals of the second switching circuit and the fifth selection filter, to execute multipath equalization, and to output an equalized signal.
