单片机MC9S08AW60脉宽调制 TPM1CH3 LS2亮度控制 KBI SEG控制亮度等级 。本工程为定时器输出PWM波测试工程实例通过对PWM占空比的调节,实现小灯的渐亮的功能,当占空比为100％时再从0％逐渐增加.PWM的周期一定要足够的快,否则其输出电压的波动范围很大,且测不出一个稳定的电压值,这样通过就观察不到小灯渐亮效果. 另外,在改变PWM的周期和占空比之前和之后要分别禁止和使用。(MC9S08AW60 pulse width modulation TPM1CH3 LS2 brightness control KBI SEG brightness level. This project is an example of testing the output PWM wave of the timer. By adjusting the duty ratio of the PWM, the function of the small lamp gradually brightening is realized. When the duty ratio is 100%, the period of the small lamp gradually increases from 0%. The period of the PWM must be fast enough. Otherwise, the fluctuation range of the output voltage is large and a stable voltage value can not be measured, so the effect of the gradual brightening of the small lamp can not be observed. In addition, the period of the PWM is changed. Before and after duty cycle should be prohibited and used separately.)

：LTE(Long Term Evolution，长期演进)系统中的小区初始搜索过程通过分别检测主同步信号(Primary Synchronization Signal，PSS)和辅同步信号(Secondary Synchronization Signal，SSS)来完成，搜 索结果包括小区组ID、符号定时、频偏估计、组内小区ID以及帧定时[1]。然而，若接收信号   1IDN  2IDN 中存在整数倍频偏，则由于时域的相位旋转，主同步信号将很难用传统的相关算法检测到。提出一种主同步信号与整数倍频偏联合检测的方法，即使存在整数倍频偏，也能得到正确的符号定时。辅同步信号采用的是非相干的差分相关检测[2]，仿真表明，与传统的匹配滤波算法相比，可以有效的对抗信道时延扩展和载波频偏，适用于高速场景下时分双工(Time Division Duplex，TDD)LTE系统的同步。(In LTE systems, the initial cell search process is completed by detecting the primary synchroniza-tion signal and the secondary synchronization signal. The searching results include cell ID group, symbol timing, frequency offset estimation, intra group cell ID and frame timing[1]. However, if integer frequency offset presents in the received signal, due to time-domain phase rotation, the primary synchronization signal will be difficult to detected using the conventional correlation algorithm. A new joint detection method for integer frequency offset and primary synchronization signal is proposed, which can get the correct symbol timing even if the presence of integer frequency offset. Secondary synchronization signal is processed using the differential non-coherent correlation detection method[2]. Simulations show that compared with the tradi-tional matched filtering algorithms, it can effectively combat the channel delay spread and carrier frequency offset and especially suitable for )
