Patent ID: 7822163

Claim:
A method of synchronization of performed by a network device, comprising: obtaining a sequence of symbols transmitted according to a predetermined cover sequence, wherein a given symbol of the sequence of symbols comprises a number of samples and wherein the sequence of symbols comprises a sequence of samples; determining an estimation metric, M sa , by comparing pairs of symbols from the sequence of symbols; and comparing the estimation metric to a threshold value to determine frame synchronization; wherein M sa = ∑ l = 0 l max ⁢ ⁢ ∑ k = 0 k max ⁢ ⁢  r ⁡ ( k + N s ⁡ ( j · l + m ) ) ± r ⁡ ( k + N s ⁡ ( j · l + m ) + n · N s )  , where r(i) is the ith sample, where l max is determined according to the number of symbol pairs compared, where k max is determined according the number of samples per symbol, where N s is the number of samples per symbol, and where j, m, and n are determined according to the predetermined cover sequence.
