Frequency offset correction (FOC) is essential for a coherent optical orthogonal frequency-division multiplexing (CO-OFDM) system. In this paper, we proposed a robust and efficient FOC algorithm by designing training symbols in frequency domain. This algorithm has an advantage in overcoming imperfect frequency response induced by transmitter devices and physical channel implementations. To further...

We introduce a semi-automated algorithm to extract urban road from high-resolution RS image using the Probabilistic Topic Models. First of all, an image collection is generated from a high-resolution image by partitioning it into densely overlapped sub-images. The image collection is divided into two subsets, i.e., training images and testing images. The training images are used to estimate the number...
