METHOD AND DEVICE FOR GENERATING TRANSMISSION LINE INFORMATION, AND ERROR CORRECTION DECODER

PROBLEM TO BE SOLVED: To enable acquiring correct transmission line information even when the influence of a noise is large. SOLUTION: The input signal is applied to a data demodulator 31 and a pilot demodulator 32; to be demodulated. A demodulation signal amplitude sequence rX} is acquired from the...

Summary:PROBLEM TO BE SOLVED: To enable acquiring correct transmission line information even when the influence of a noise is large. SOLUTION: The input signal is applied to a data demodulator 31 and a pilot demodulator 32; to be demodulated. A demodulation signal amplitude sequence rX} is acquired from the output of the data demodulator 31, and a pilot signal sequence p} is acquired from the output of the pilot demodulator 32. The pilot signal sequence p} is applied to an estimation apparatus 33 of transmission line information, and transmission line information LC is acquired as an output of the estimation apparatus 33 of transmission line information. The transmission line information LC on the output of the estimation apparatus 33 of the transmission line information and the demodulation signal amplitude sequence rX} are multiplied in a multiplier 34 to be applied to an error correction decoder 35, then a decoding sequence having few errors can be acquired.
