ABSTRACT:
The present invention is directed to an apparatus for symbol timing detection for a wireless communication system. According to the present invention, the samples of the output of an analog-to-digital converter are utilized prior to the completion of the automatic gain control function to detect symbol timing using autocorrelations of the samples, and a structure supporting an average window size and a delay value is provided to optimize the complexity and allow a signal demodulation of high reliability.
