1. be used for communication system with a connection (V1, the transmission rate that changes during V2) transmit these existing data that connect (D1, method D2), wherein-described connection (V1, transmission rate V2) can adopt one first value to compare the second higher value with one with described first value,-for described connection (V1, V2), first value of described transmission rate occurs more continually than second value of described transmission rate,-and be useful on to the data that will transmit (D1, D2) carrying out the mutually orthogonal spread spectrum coding (SC1..256) of spread spectrum and being used for, the data behind the spread spectrum to be carried out at least two scramblers (VC1..18) of scrambling available,Described method has following steps:

  • -in order to reach first value of described transmission rate, described connection (V1, (D1 D2) utilized spread spectrum coding (SC1 unique concerning described connection to data V2) before it is transmitted, SC2) carry out spread spectrum and utilize first scrambler (VC1) to carry out scrambling and and then be transmitted-and in order to reach second value of described transmission rate, the data (D1) of described connection (V1) were divided into two groups of (G11 before it is transmitted, G12), the data of first group (G11) are utilized one of spread spectrum coding (SC1) to carry out spread spectrum and are utilized first scrambler (VC1) to carry out scrambling afterwards, and the data of second group (G12) are utilized one of spread spectrum coding (SC1;

    SC3) carry out spread spectrum and utilize second scrambler (VC2) to carry out scrambling, and and then described data be transmitted,(D1 D2) constitutes and to have header (H1-the data that wherein will transmit;

    H2) and the packet of data division (DA),If-the wherein current data packets for transmission of wanting has first length, then there is first value of described transmission rate,If the wherein current data packets for transmission of wanting has second length longer than first length, then there is second value of described transmission rate.
