COMMUNICATIONS SYSTEMS, METHOD AND DEVICE IN MIMO SYSTEMS WITH DOMAIN SPREADING |
摘要 |
<p>A communications system (101) comprises a transmitting device (102) and a receiving device (114). The transmitting device (102) comprises at least T transmit antennas (116), means for spreading (110) each of T symbols (x) in the time domain only to produce T time sequences of chips (x1, x2, x3 = X) and transmitting the T time sequences of chips (X) from the T transmit antennas (116) respectively. The receiving device (114) comprises at least R receive antennas (118), means for despreading (120) the R time sequences of chips (y1, y2, y3 = Y) received from the transmitting device (102) at the R receive antennas (118) respectively to a produce R received symbols (z), and means for processing (116-1) the R received symbols (z) to produce an estimate of the T symbols (x) spread at the transmitting device (102).</p> |
