Radio communication system, transmitter and decoding apparatus employed in radio communication system
First Claim
1. A radio communication system with a transmitting station which multiplexes different data and transmits multiplexed data to a receiving station, comprising:
- a transmitting station comprising;
a first encoding unit configured to generate plural parity information by using the different data;
a second encoding unit configured to encode each of the plural parity information and each of the different data to produce plural encoded data;
a modulation unit configured to modulate carriers by the plural encoded data to generate plural modulated signals; and
a multiplex unit configured to multiplex the plural modulated signals for outputting a multiplexed signal; and
a receiving station comprising;
a demultiplex unit configured to demultiplex the multiplexed signal transmitted from the transmitting station into the plural modulated signals;
a demodulation unit configured to demodulate each of the modulated signals demultiplexed by the demultiplex unit to produce plural demodulated signals;
a first decoding unit configured to decode each of the demodulated signals according to a decoding scheme corresponding to an encoding scheme of the second encoding unit to produce plural decoded signals; and
a second decoding unit configured to decode each of the decoded signals according to a decoding scheme corresponding to an encoding scheme of the first encoding unit to obtain the different data.

Abstract
Radio-communication-system includes transmitting-station and receiving-station. The transmitting-station includes first-encoding-unit configured to generate plural parity-information by using the different-data, second-encoding-unit configured to encode each of the plural parity-information and each of the different-data to produce plural encoded-data, modulation-unit configured to modulate carriers by the plural encoded-data to generate plural modulated-signals, and multiplex-unit configured to multiplex the plural modulated-signals for outputting a multiplexed-signal. The receiving-station includes demultiplex-unit configured to demultiplex the multiplexed-signal transmitted from the transmitting-station into the plural modulated-signals, demodulation-unit configured to demodulate each of the modulated-signals demultiplexed by the demultiplex-unit to produce plural demodulated-signals, first-decoding-unit configured to decode each of the demodulated-signals according to a decoding-scheme corresponding to an encoding-scheme of the second-encoding-unit to produce plural decoded-signals, and second-decoding-unit configured to decode each of the decoded-signals according to a decoding-scheme corresponding to an encoding-scheme of the first-encoding-unit to obtain the different-data.
