In this paper, Using a 2D photonic crystal and a novel square ring resonator,several compact and simple structures have been introduced in the present paper toconstruct optical add/drop filters and multi-channel filter. The difference structures hasbeen designed and simulated by using the proposed square ring resonator and differentdropping waveguides. To do analyses, th...

We propose an iterative design algorithm for jointly optimizing source and channel codes. The joint design combines channel-optimized vector quantization (COVQ) for the source code with rate-compatible punctured convolutional (RCPC) coding for the channel code. Our objective is to minimize the average end-to-end distortion. For a given channel SNR and transmission rate, our joint source and cha...

Deep learning-based joint source-channel coding (JSCC) has shown excellent performance in image and feature transmission. However, the output values of JSCC encoder are continuous, which makes constellation modulation complex dense. It is hard expensive to design radio frequency chains for transmitting such full-resolution points. In this paper, two methods mapping finite proposed real system i...

Abstract In recent years, microfluidic chips have been widely used in food safety, environment detection, clinical diagnosis and biochemical. However, Digital chips(DMF) are attracting more eyes because picoliter-microliter-sized sample droplets can be accurately automatically manipulated. this paper, a method of design electrode channel height is studied to improve the efficiency voltage drivi...
