Abstract  Abstract

PROBLEM TO BE SOLVED: To enhance cost-effectiveness and to simply realize high bit rate by transmitting a virtual transmitting signal through the partial aggregation of a virtual sub-channel by using propagation information.

SOLUTION: A first unit 12 transmits a diagonal matrix D to a channel encoder/modulator 24 in transmission from the first unit 12 to the second unit 14 so as to encode and modulate an information stream from a data source 28. The channel encoder/modulator 211 encodes and modulate the information stream forms plural sub-information streams which differ in accordance with the non-zero value of the diagonal matrix D and generates a virtual transmitting signal. The virtual transmitting signal is expressed as a vector and its respective configuration components are transmitted by the respective virtual sub-channels. Moreover a unitary conversion block 30 executes the unitary conversion of the virtual transmitting signal by multiplexing the virtual transmitting signal through the use of the conjugate transposition of a unitary matrix ?. Finally the first unit 12 utilizes the result of unitary conversion 30 so as to generate the base band version of the actual transmitting signal.
