  • Training sequence for symbol boundary detection in a multicarrier data transmission system
    Publication number: 20050276339
    Abstract: An improved training sequence for acquiring symbol boundary timing at a receiver of a data transmission system is disclosed. One aspect pertains to an improved training sequence wherein groups of identical symbols are transmitted by a transmitter. These symbols can be supplied to the transmitter in a time domain or a frequency domain manner. The improved training sequence facilitates symbol boundary determination at a receiver.
    Type: Application

  • Method and system for determining symbol boundary timing in a multicarrier data transmission system
    Publication number: 20050276340
    Abstract: Improved techniques for acquiring symbol boundary timing at a receiver of a multicarrier data transmission system during a training sequence are disclosed. One aspect is symbol boundary determination at a receiver wherein minimal interference is used as a criterion in selecting from a plurality of potential symbol boundary timings. The symbol boundary determination at the receiver can be performed in a time domain or a frequency domain manner. Another aspect pertains to an improved training sequence wherein pairs of identical symbols are transmitted by a transmitter. These symbols can be supplied to the transmitter in a time domain or a frequency domain manner.
