Abstract
This disclosure describes systems, methods, and devices related to frequency offset tracking in optical signals. A device may identify modulated light received from a light source, wherein the modulated light is received at a frame rate, and wherein the modulated light is associated with pixel clusters. The device may determine light samples based on the pixel clusters, the light samples including a first light sample and a second light sample. The device may determine a vector norm between the first light sample and the second light sample using an oversampling factor. The device may determine that the vector norm is below a threshold. The device may determine a start frame delimiter (SFD) based on the vector norm. The device may demodulate the symbol based on the oversampling factor.
