Second, this paper design the simulation scheme of bicm for comparing the performance over fading channel and awgn channel that combine 2 / 3 rate, 4 states punctured convolutional code with 8psk modulation, matching block interleave or random interleave, transform through rayleigh channel or awgn channel and use the way that combine coherent demodulation with viterbi decoding in receiver. design the scheme of bicm _ id that use the iterative decoding technique and the scheme of tcm for compare
為了驗證bicm和bicm _ id在衰落通道和加性高斯白噪聲通道（ awgn ）下的性能，設計了一個2 / 3碼率， 4狀態的鑿
孔卷積碼經過塊交織或隨機交織，與8psk調制相結合，在rayleigh通道下或awgn通道下傳輸，接收端採用相干解調與維特比譯碼相結合的bicm方案，在接收端引入迭代反
饋譯碼的bicm _ id方案，以及與之相比較的tcm方案。
Abstract : this article discusses a control method of sensors syncretic, when an assembly process is controlled by position, force feedback and vision, the assembly is high speed and high precision, it is very important that the control method accords with request of intelligentized assembly of robot and can be used on intelligentized produce line
文摘:提出了一種多傳感器融合的控制方法，利用位置、力反
饋和視覺控制裝配過程，使得高速高精度的軸
孔裝配得以實現，該控制方法順應了機器人智能化裝配的要求，可應用於智能化裝配生產線上。
The upper end axis and screw on cylinder body accord with namur standard, it is for installation of feedback device of valve supply and valve locator
上端軸以及缸體上的螺孔符合namur標準。供閥位反饋裝置以及閥門定位器的安裝。
