Abstract： |
The present invention discloses a self adaptation multiple input/output transmitting/receiving system and method. Said transmitter includes serial-to-parallel converter, plurality of channel encoder, plurality of constellation mapping unit, plurality of sending power regulator, said receiver includes transmittal mode zero forcing/minimum mean square error detector, plurality of received power regulator, plurality of constellation demapping unit, plurality of channel decoder, and parallel to serial converter. Said transmittal mode selector generates information concerning adoptive aerial congregation, relative constellation mapping mode information and sending power information, providing these information to transmitter and receiver relevant unit, thereby adjusting sub code stream number, constellation mapping mode and sending power. Said invented method and system can reach obvious performance gain and need less feedback information. |
