Patent ID: 8077591

Claim:
A process for generating candidate preambles for evaluation for maximum Carrier to Interference plus Noise Ratio (CINR) from the subcarriers resulting from a Fast Fourier Transform (FFT) of a received preamble, the process operative on a signal processor and having the steps: a step for generating an ideal preamble from an ideal preamble generator indexed by a first iteration variable; a step for performing an integer offset of the subcarriers of the received preamble to generate an integer offset preamble controlled by a second iteration variable; a step for decimating the integer offset preamble to generate a decimator output; a multiplication step for multiplying the decimator output by a value selected from said ideal preamble generator using said first iteration variable; where each combination of values of said first iteration variable over a first iteration variable range and said second iteration variable over a second iteration variable range thereby forms one of said candidate preambles.
