The two-dimensional (2-D) doubly stochastic Gaussian (DSG) model was introduced by one of the authors to provide a complete model for spatial filters which adapt to the local structure in an image signal. Here we present the optimal estimator and 2-D fixed-lag smoother for this DSG model extending earlier work of Ackerson and Fu. As the optimal estimator(More)

This paper. investigates error performance issues concerning IEEE 802.6 Metropolitan Area Network (MANs) which will be based on fiber transmission systems. We study the error protection requirements for MAN cell headers and propose a simple CRC-based scheme to provide single bit correction and multiple bit detection. The functions of adaptation layer for(More)
