A novel RB-WC-FI-FB (robust worst-case frequency invariance forward-backward) wideband beam former is proposed in this paper. It is developed to improve the robustness against estimation errors of direction of arrival (DOA) and limited sample number, as well as reduce the number of constraints. By incorporating forward-backward estimation and worst-case performance optimization method into the linearly...
We propose and develop a simple hybrid integration solution for a 100 Gb/s dual polarization quadrature phase shift keying coherent receiver. The cost-effective, precise, and passive alignment technique can be used to couple four output waveguides of planar lightwave circuits (PLCs) based 90 optical hybrid (OH) with a 1 4 photodiode (PD) array directly, adopting an infrared charge-coupled...
A method of rapid secret sharing scheme based on STAR codes is proposed. Due to the characteristic of array codes such as STAR codes, the computation in secret sharing scheme need only XOR operation on GF(2), which is distinguished with the modulation and other complex operation on GF(q) in the traditional schemes. Thus, it's more rapid and suitable for large capacity secret sharing, and also appropriate...
We present a new class of erasure codes of size ntimesn (n is a prime number) called T-code, a new family of simple, highly fault tolerant XOR-based erasure codes for storage systems (with fault tolerance up to 15). T-code is not maximum distance separable (MDS), but has many other advantages, such as high fault tolerance, simple computability, and high efficiency of coding and decoding. Because of...
