摘要： A transmitter station and receiver station have common maximum number of transmission bits per symbol of each subcarrier and information of encoding types to be selected. The transmitter station selects the modulation type from the propagation path quality of each subcarrier, executes encoding with the encoding type corresponding to the number of bits for communication with the selected modulation type, distributes the maximum number of transmission bits per symbol of each subcarrier by dividing the code, and transmits the data through modulation of only the number of bits for communication with the selected modulation type among distributed bits in each subcarrier. The receiver station executes demodulation by selecting the modulation type used for demodulation from the propagation path quality, summarizes the demodulation result with addition of reception of the signal having a zero degree of likeliness for the number of wanted bits, and executes decoding to the result of demodulation.

摘要： In a radio communication system, transmitter and receiver stations share information on a maximum number of bits communicated per symbol. The transmitter station encodes a signal with sufficient error correcting capabilities to create a codeword. The transmitter station allocates the bits from the codeword to each symbol, modulates the symbols using a modulation type which processes symbols each having a number of bits equal to or smaller than the maximum number of bits per symbol, and transmits the modulated symbols. The receiver station demodulates the symbols using a modulation type which processes a larger number of bits per symbol as the transmission path quality is higher from among modulation types which process symbols having a number of bits equal to or smaller than the maximum number of bits per symbol.

摘要： A radio communication system includes a first radio station for dividing codewords into communication units and transmitting the divided codewords by modulating them in every communication unit, and a second radio station for coupling and decoding signals obtained by demodulating the communication units. The radio stations have common information of first bits, equal to maximum bits per symbol of the communication units, and an encoding type list. The first station modulates and transmits the communication units with a modulation type with second bits. The second radio station receives the communication units modulated by the first radio station, demodulates the communication units with a modulation type with third bits, combines and decodes the demodulated signals with encoding types in the encoding type list, and obtains a result of the decoding, as reception information, by an encoding type in which no error is detected in the result of decoding.

摘要： A radio communication system for enabling control of a modulation scheme following variation in the propagation channel and control of a coding rate in a small amount of delay and arithmetic operation. In order to attain the object explained above, a transmitter station and a receiver station use in common the information of the maximum number of bits used for communication of each symbol. The transmitter station generates codeword by previously encoding the communication signal with the code having sufficient error correcting capability, assigns, to each symbol, the codeword to result in the maximum number of bits per symbol, and modulates and transmits the bits using the modulation scheme in which the number of bits per symbol is equal to or less than the maximum number of bits per symbol. Meanwhile, the receiver station demodulates, for each symbol, the bits with the modulation scheme, in which the number of bits per symbol is larger as the propagation channel quality is higher, among the modulation schemes in which the number of bits per symbol is less than the maximum number of bits per symbol and summarizes the demodulation results and executes the decoding process by adding the signal of zero likelihood to restore the shortage when the total sum of the number of bits per symbol in the modulation scheme used for the demodulation becomes equal to or larger than the predetermined value.
