Method for transmitting pre-equalized digital data, and transmitting base implementing such a method |
摘要 |
<p>A method for transmitting digital data on a communication channel, between a transmitter base comprising N transmission antennas and K receivers. A signal carrier of frequency f0 and M sub-carriers of index m are used, adapted to transport K streams of digital data sk in parallel between the transmitter base and each receiver. The method comprises a step in which N.M complex symbols tn(m) are calculated from K.M symbols sk(m), by t n ( m ) =∑k = 1 K αk · H k , n * ( m ) · s k ( m ) , where * denotes a complex conjugate, Hk,n(m) is a complex value estimating the transfer function of the communication channel between the transmission antenna n and the receiving antenna k at a corresponding frequency of the sub-carrier m, andαk is a normalization coefficient.</p> |
