Patent ID: 8199863

Claim:
A multiple-antenna space multiplexing system using enhancement signal detection comprising: a code modulation module ( 101 ) for coding and modulating bit information; a signal transmission module ( 102 ) for transmitting the modulated signals; a signal reception module ( 201 ) for receiving the signals; a signal form transform module ( 202 ) for transforming form of a channel matrix H and the received signal vector r; a signal detection module ( 203 ) for detecting the received signals; a signal reconstruction module ( 204 ) for reconstructing the detection results of in the signal detection module, and obtaining a detected signal {tilde over (s)}; a demodulation decoding module ( 205 ) for demodulating and decoding the output of the signal reconstruction module, and outputting bit information, wherein the signal transmission module transmits signals as following principles: a signal waiting to be transmitted is s, assuming that quasi-static fading channel H remains the same between adjacent time block T 1 and T 2 ; in time block T 1 , the transmission signal is s T 1 =Re(s)+jIm(s); in time block T 2 , the transmission signal is s T 2 =Im(s)+jRe(s), where Re(s) indicates a real part of complex signal, Im(s) indicates an imaginary part of complex signal.
