Abstract:
1. A reception apparatus in a multicarrier transmission system which subjects a plurality of subcarriers, which are orthogonal with each other, to multicarrier modulation and transmits digital data, the reception apparatus comprising: a multicarrier demodulation section for receiving a multicarrier modulation signal, demodulating the received multicarrier modulation signal, and outputting demodulation vectors obtained by the demodulation; a canceling filter section for receiving the demodulation vectors, subjecting the demodulation vectors, which respectively correspond to the subcarriers neighboring in a frequency axis direction, to filtering processing which cancels inter-carrier interference, and outputting filtered demodulation vectors obtained by the filtering processing; and a vector demodulation section for determining received data from the filtered demodulation vectors and outputting the data, wherein the multicarrier demodulation section demodulates modulation vectors which modulate the subcarriers in a one-on-one relationship, and the filtered demodulation vectors uniquely correspond to precoded modulation information obtained by subjecting transmitted data to precoding processing in a transmission apparatus, and a correspondence relationship thereof is determinable in the vector demodulation section.
