Title:
WIRELESS COMMUNICATION SYSTEM, TRANSMITTER APPARATUS, RECEIVER APPARATUS, AND WIRELESS COMMUNICATION METHOD
Document Type and Number:
WIPO Patent Application WO/2012/108346
Kind Code:
A1
Abstract:
A receiver apparatus comprises: a means that divides, by N, the spectrum of a signal, which is to be transmitted, to perform a spectrum revision, thereby reducing the occupied bands and that receives, as a received signal, a signal transmitted from a transmitter apparatus; a means that error-corrects and decodes the received signal by use of the bandwidth of the signal to be transmitted, thereby generating a first decoded signal; a means that generates a transport replica signal from the first decoded signal and that divides, by N, the spectrum of the transport replica signal, thereby generating N sub-replicas; a means that uses the N sub-replicas and the received signal to restore the spectrum of the signal to be transmitted from the transmitter apparatus, thereby generating a compensated received signal; and a means that decodes the compensated received signal to generate a second decoded signal.
