From: Compressive sampling-based CFO-estimation with exploited features
Examples of the compressibility of CFO estimation metrics for noise-free cases. Where N=64, P=64, T s =10−9s. a Δ f.T s =−0.4976 (normalized CFO is near to −0.5); b Δ f.T s =−0.2441 (normalized CFO is between −0.5 and 0); c Δ f.T s =0.3241 (normalized CFO is between 0 and 0.5); and d Δ f.T s =0.4757 (normalized CFO is near to 0.5)
