  • Method of determining a symbol transmission format in a transmission system and system
    Patent number: 6314113
    Abstract: A method and apparatus for determining the transmission format of complex symbols in a received signal which is formatted in complex symbol blocks. Each block has a first occurrence (GIk) of a sequence of complex symbols and second occurrence (gIk) of the same sequence of complex symbols. A correlation between the first and second occurrences is effected by means of acquisition and correlation time windows, the transmission format being determined by searching for maximum correlation between the first complex symbol sequence and the second complex symbol sequence via synchronization of the windows with the received signal so that the windows select the first occurrence and the second occurrence of complex symbols, respectively. Particularly useful in a digital transmission system employing Orthogonal Frequency Division Multiplexing (OFDM).
