By adjusting the positions and angles of the two DVD optical pick-up heads, the relative distance of the two laser spots can be equivalent to one quarter of the grating pitch. When the grating moves, the surface profile of the grating can be measure directly, in order to obtain the two quadrature sinusoidal signals. Then by counting the zero crossing of these two quadrature sinusoidal signals and calculating the interpolation value of these two quadrature sinusoidal signals, the moving direction and moving displacement value of the grating can be obtained.

This invention discloses an IC phone communication method based on the FSK mode including: loading and transmitting ciphered sequences, ciphered card information, called number information and other interaction information between an IC terminal and a process platform in the mode of FSK information, in which, the platform authenticates the authority and charges, if the deduction at the IC terminal is correct, then it sends signals of anti-stealing making phone calls periodically to the platform, which differentiates the correctness of the signals, if they are wrong, it releases the call, when the communication is finished and the calling rings off first, the platform receives the identification signals of the ring-off of the calling to cut off the call of the called side and release the voice channel between the platform and the called side, then processes balance information and releases the call finally.

本发明公开了一种基于频移键控方式的IC卡电话通信方法，其主要方案是IC卡终端与处理平台之间通过FSK信息方式承载和传输加密序列、加密卡信息、被叫号码信息及其它交互的信息，由处理平台进行鉴权和计费；如果IC卡终端扣费正确则周期性向处理平台发送防盗打信号，处理平台鉴别防盗打信号的正确性，如果错误则释放呼叫；当通信结束后主叫先挂机时，处理平台收到主叫挂机标识信号后首先切断被叫侧的呼叫，释放处理平台与被叫侧之间的话路，然后再进行余额信息的处理和最后释放呼叫。使用本发明提出的方法，使得IC卡终端与处理平台之间的信息交互流程更加简单、清晰，提高了信息交互效率，并能及时释放话路，节约中继资源。

Both of them are borrowed from the idea of WRELAX algorithm, which is originally used to multipath time delay estimation for known signals, and applied to the cyclic auto and cross correlation of the reference and received signals.
