Abstract
Apparatus and methods for symbol timing synchronization in a direct-sequence spread-spectrum receiver may use non-coherent integration, thresholding, peak selection, and curve fitting to determine appropriate timing instants at which to select despread samples for further processing, such as demodulation and decoding. The curve fitting may be used to search backwards and/or forwards in time to obtain the timing instants.
