1. receiving system comprises:

  • Receiving element receives a plurality of modulation signals that send from the dispensing device with many antennas, and described a plurality of modulation signals are the modulation signal that differs from one another, send respectively from described many antennas;

    The channel variation estimation unit is asked the channel estimation value of each modulation signal of described a plurality of modulation signals;

    The QR resolving cell, carrying out QR by the channel estimation value to each modulation signal of described a plurality of modulation signals decomposes, calculate upper triangular matrix, and use described upper triangular matrix and described modulation signal, generate a plurality of decomposed signals that comprise first decomposed signal and second decomposed signal at least, described first decomposed signal is, in described a plurality of decomposed signals, the signal that its modulation signal that comprises is minimum, and described second decomposed signal is, includes the signal of the modulation signal that other modulation signal and described first decomposed signal comprised;

    The partial bit identifying unit uses first row of described first decomposed signal and the described upper triangular matrix corresponding with described first decomposed signal, judges the highest bit of likelihood in described first decomposed signal;

    The backup signal location arithmetic element, use second row of the highest bit of likelihood in described first decomposed signal, described second decomposed signal and the described upper triangular matrix corresponding, from described second decomposed signal, carry out the reduction of backup signal location with described second decomposed signal;

    AndThe likelihood of each bit for the backup signal location after cutting down, is asked in backup signal location decision unit in a plurality of bits that send by described a plurality of modulation signals.
