    摘要: A method for generating a preamble of a data unit for transmission via a communication channel includes generating a first field of the preamble using one of a first sequence or a second sequence, such that the first sequence and the second sequence are complementary sequences such that a sum of out-of-phase aperiodic autocorrelation coefficients of the first sequence and the second sequence is zero; generating, using the other one of the first sequence or the second sequence, an indicator of a start of a second field of the preamble, the second field associated with channel estimation information, such that the indicator of the start of the second field immediately follows the first field; and generating the second field of the preamble.

    摘要: The frequency spectrum of a transmission system is spread in the transmitter (1) by information bit encoding by means of Golay complementary sequence pairs. The spectrum is picked up in the receiver (2) and passed through a filter that is adapted to the characteristics of said frequencies enabling detection of digital levels corresponding to the transmitted original information. If θ pairs of orthogonal sequences, Α amplitudes for data modulation and N-PSK modulation are used, it is possible to obtain transmission speed (C) which equals formula (I), wherein B is the null-to-null bandwidth used in Hertz. This makes it possible to improve quality in comparison with other digital communication systems using spread-spectrum techniques and CDMA. A process gain independent of transmission speed is obtained.
