These images, obtained as a result of acoustic response of soft-biological tissues are called Tissue Reflectivity Function (TRF). TRF suffers from speckle patterns due to non-homogeneous nature of soft tissues being interrogated. The interference of reflected beam develops random patches of bright and dark spots. The reduced spatial resolution in the axial direction worsened as a function of distance from the transducer probe affects the diagnostic significance of ultrasonography. We design an optimization framework with consideration to Gaussian and speckle noise characteristics in the form of two data fidelity terms. To preserve edges during the iterative reconstruction process, we introduce Total Variation (TV) regularization term as well. We have conducted experiments on artificially corrupted synthetic data and simulated and real ultrasound data. Experimental results using several metrics supported by the visual results show improvement over state-of-the-art techniques for ultrasound image restoration.","PeriodicalId":126759,"journal":{"name":"2020 7th International Conference on Signal Processing and Integrated Networks (SPIN)","volume":"194 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116059083","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The architecture of the UART transmitter has a baud rate generator, parity generator, transmitter finite state machine (FSM) and parallel in serial out register (PISO). UART receiver has a baud rate generator, negative edge detector, parity checker, receiver finite state machine (FSM) and serial in parallel out (SIPO) register. The baud rate generator of both transmitter and receiver is the same, so the baud rate of transmitter/receiver is the same. Baud rate generator is the same as the frequency divider circuit. The data frame of the UART transmitter is 1 start bit, 8 transmits data bits, 1 parity bit and 1 stop bit. The baud rate of the transmitter and receiver is 4 Mbps using the system clock of 64 MHz’s. Implementation, simulation, and synthesis is done Xilinx Vivado 2016.2 version tool. The design is verified using simulated waveform and synthesized on the FPGA Zed board.","PeriodicalId":126759,"journal":{"name":"2020 7th International Conference on Signal Processing and Integrated Networks (SPIN)","volume":"36 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128590629","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

There are mainly three most common ways in which an optical amplifier may be used in an optical link. There are many types of optical amplifiers available one of which is the Semiconductor optical amplifier (SOA). The working of an SOA is just like that of a LASER, the only difference between a LASER and an SOA is that the later doesn’t have feedback mechanism as present in the case of former. Stimulated emission causes the amplification of entering light waves. An effect known as Cross phase modulation has been utilized in this work in order to exploit the non-linear properties of optical medium. Cross phase modulation takes place when two or more optical fields pass through the same optical medium simultaneously, the change in refractive index due to one optical field causes phase modulation of the other optical fields. This phenomenon is widely used to detect and study the non-linear properties of the link or the optical medium under consideration.In this work we have proposed schematics for full-adder and full-subtractor circuits. We have provided two separate circuit designs which has the schematic of Sum/Difference in the first one and Carry/Borrow in the second. Considering an input sequence of 10 bits we have simulated our schematic designs in OptiSystem 16 research software. The observations have been incorporated in the results section.","PeriodicalId":126759,"journal":{"name":"2020 7th International Conference on Signal Processing and Integrated Networks (SPIN)","volume":"37 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123838487","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
