A new method of sinusoid estimation in noise using multi-level crossing interval information is presented. Using the statistics of level crossing intervals a sinusoid detection criterion is formulated and an expression for threshold SNR is derived for any single level. The analysis is extended to a pooled set of multi-level crossing intervals resulting in a better SNR threshold of detecting a sinusoid. It is demonstrated that the multi-level crossing information is more robust than single level crossing information and the robustness improves with increasing contribution from higher levels.
