Claim Text:
1. A method, comprising: receiving a signal from a radio channel and computing frequency domain symbols of the received signal and a reference signal through a Fast Fourier Transform (FFT); dividing the received signal and the reference signal into a plurality of frequency bins, wherein the received signal in each frequency bin with a Primary Synchronization Code (PSC) is a first-group candidate; performing correlating measures between the received signal and the reference signals over a predefined time interval and de-mapping from the frequency domains through an Inverse Fast Fourier Transform (IFFT); obtaining correlation and peak values for each of the first-group candidate and determining a channel condition based on the peak values for the first-group candidates; adaptively adjusting a multi-try number and a set of thresholds based on the determined channel condition; and performing an adaptive multi-try based peak selection to select a plurality of second-group candidates for the multi-try number of times using the set of thresholds for each corresponding candidate, wherein the second-group candidates is a subset of the first-group candidates.
