The same Two-stage decoder as above. However, when transforming the symbols prior to Viterbi decoding, the amplitude information is ignored and only the phase of the received symbol is employed in the metric computation stage.

An unsatisfactory property of particle filters is that they may become inefficient when the observation noise is low. In this paper we consider a simple-to-implement particle filter, called ‘LIS-based particle filter’, whose aim is to overcome the above mentioned weakness. LIS-based particle filters sample the particles in a Two-stage process that uses information of the most recent observation, too. Experiments with the standard bearings-only tracking problem indicate that the proposed new particle filter method is indeed a viable alternative to other methods.

電學(xué)中的測(cè)量技術(shù)涉及范圍非常廣,電流測(cè)量在電學(xué)計(jì)量中占有非常重要的位置。如何精確地進(jìn)行電流測(cè)量是精密測(cè)量的一大難題。傳統(tǒng)的電流檢測(cè)電路多采用運(yùn)算放大芯片與片外電流檢測(cè)電路相結(jié)合的方式,電路集成度很低,需要較多的接口和資源才能完成對(duì)電路的檢測(cè)。本文把所有電路部分都集成在一塊芯片上,包括檢測(cè)電阻,運(yùn)算放大器電路及模擬轉(zhuǎn)數(shù)字轉(zhuǎn)換電路,從而在電路內(nèi)部可以進(jìn)行電流檢測(cè),使電路更好的集成化。前置電路使用二級(jí)共源共柵結(jié)構(gòu)的運(yùn)算放大器,減小溝道長(zhǎng)度調(diào)制效應(yīng)造成的電流誤差。10位SAR ADC中采用電容驅(qū)動(dòng)能力強(qiáng)的傳輸門保證了模數(shù)轉(zhuǎn)化器的有效精度。比較器模塊采用再生鎖存器與遲滯比較器作為基礎(chǔ)單元組合解決精密測(cè)量的問題。本設(shè)計(jì)可以作為嵌入芯片內(nèi)的一小部分而檢測(cè)芯片中的微小電流1mA~100mA,工作電壓在1.8v左右,電流檢測(cè)精度預(yù)期達(dá)到10uA的需求。The measurement technology in electricity involves a wide range,and current measurement plays a very important position in electrical measurement.How to accurately measure current is a big problem in precision measurement. The traditional current detecting circuit adopts the combination of the operational amplifier chip and theoff-chip current detecting circuit, The circuit integration is very low, and more interfaces and resources are needed tocomplete the circuit detection.This topic integrates all the circuit parts into one chip, including detection resistance, operational amplifier circuit andanalog to digital conversion circuit. Highly integrated circuit makes the external resources on the chip more intensive,so that current detection can be carried out inside the circuit, so that the circuit can be better integrated. Thefront-end circuit of this project uses Two-stage cascade operational amplifier and cascade tube to reduce the currenterror caused by channel length modulation effect. In 10-bit SAR ADC, the transmission gate with strong capacitivedriving ability ensures the effective accuracy of the analog-to-digital converter. Comparator module uses regenerativelatch and hysteresis comparator as basic unit to solve the difficult problem of precision measurement. This topic can beused as a small part of the embedded chip to detect the micro-current in the chip 1 mA~100 mA, the working voltageis about 1.8v, and the current detection accuracy is expected to reach the requirement of 10 uA.
