Document image binarization is a crucial step towards optical character recognition and analysis. One common way to achieve image binarization is thresholding. Thresholding methods can be divided into global and local ones in terms of the regional information used in obtaining the threshold values. Both methods have their respective drawbacks. Global methods can not adapt to background variations...
We propose a novel real-time system design for multiband signal blind reconstruction using multi-coset sampling theory. Multi-channel signals are acquired under sub-Nyquist sampling frequency to perfectly reconstruct the original signal spectrum. A novel system design with Field-Programmable Gate Array (FPGA) implementation is presented in this paper. There are two main contributions in this paper...
In multiple-input multiple-output (MIMO) communications systems, a crucial role is played by channel estimation as the accuracy of estimation will have a substantial effect on the overall system performance. In this paper we consider designing precoding matrices and blind channel estimation algorithms for MIMO single carrier with frequency domain equalization (MIMO-SC-FDE) systems. By deriving the...
