Rate-Distortion (RD) performance of Distributed Video Coding (DVC) is considerably less than that of conventional predictive video coding. In order to reduce the performance gap, many methods and techniques have been proposed to improve the coding efficiency of DVC with increased system complexity, especially techniques employed at the encoder such as encoder mode decisions, optimal quantization, hash methods etc., no doubt increase the complexity of the encoder. However, low complexity encoder is a widely desired feature of DVC. In order to improve the coding efficiency while maintaining low complexity encoder, this paper focuses on Distributed Residual Video Coding (DRVC) architecture and proposes a simple encoder scheme. The main contributions of this paper are as follows: 1) propose a bit plane block based method combined with bit plane re-arrangement to improve the dependency between source and Side Information (SI), and meanwhile, to reduce the amount of data to be channel encoded 2) present a simple iterative dead-zone quantizer with 3 levels in order to adjust quantization from coarse to fine. The simulation results show that the proposed scheme outperforms DISCOVER scheme for low to medium motion video sequences in terms of RD performance, and maintains a low complexity encoder at the same time.

According to the problem existing in the teaching of microwave technology, such as the course was abstract, difficult and complex. The microstrip BPF (Band Pass Filter) design is adopted in the practical teaching of microwave technology, including calculating, soft simulation, optimization, layout design and simulation. The students can easily understand and enhance their professional ability.

Microwave technology is a compulsory course for the students of electronic engineering, and it is also one of the most difficult and abstract acknowledged courses for the students. Therefore, it is very important to inspire students' interest, promote their studying efficient, and change their passive ways of studying. In this paper, in order to improve the understanding and innovative capability of students, the reform and research on the teaching of microwave course is proposed.
