bison源代码.bison 是替代yacc的语法分析程序生成器. yacc是 Yet Another Compiler Compiler的缩写. bison又是什么呐 是一个生成可以分析文本文件结构的程序的程序. 用户不用直接编写程序而只用确定好如何分析这些文本文件的规则就可以了. 这种文本结构应用的例子举不胜举, 其中一个就是计算器(calculator).

A system simulation environment in Matlab/Simulink of RFID is constructed in this paper. Special attention is emphasized on the analog/RF circuit.Negative effects are concerned in the system model,such as phase noise of the local oscillator,TX-RX coupling,reflection of the environment, AWGN noise,DC offset,I/Q mismatch,etc.Performance of the whole system can be evaluated by changing the coding method,parameters of building blocks,and operation distance.Finally,some simulation results are presented in this paper.

Squaring circuits are an important building block for impulse-radio UWB non-coherent receivers. This work proposes a squarer, based on the quadratic law of saturated transistors. Such a circuit has already been proposed for lower frequency applications, therefore this work focuses on the extension to ultra wide bandwidth, with particular care to the consequences related to the deviation from the ideal quadratic law of 0.18μm CMOS transistors.

This paper presents the key circuits of a 1MHz bandwidth, 750kb/s GMSK transmitter. The fractional-N synthesizer forming the basis of the transmitter uses a combined phasefrequency detector (PFD) and digital-to-analog converter (DAC) circuit element to obtain >28dB high frequency noise reduction when compared to classicalfrequency synthesis.
