Offset-CS-Algorithm-in-LTE
：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 )

STM8--ADC-CHANGE
在许多的单片机应用系统中，都需要A/D转换器，将模拟量转换成数字量。在STM8单片机中，提供的是10位的A/D，通道数随芯片不同而不同，少的有4个通道，多的则有16个通道。
下面的实验程序首先对A/D输入进行采样，然后将采样结果的高8位（丢弃最低的2位），作为延时参数去调用延时子程序，然后再去驱动LED控制信号。因此不同的采样值，决定了LED的闪烁频率。当旋转ST三合一开发板上的电位器时，可以看到LED的闪烁频率发生变化。
(In many microcontroller applications require the A/D converter to convert analog into digital. STM8 microcontroller, providing a 10-bit A/D channel number with the chip, little has four channels, more than 16 channels. The following experimental procedure first sampling A/D input, then the sampling results 8 (drop the lowest 2), as the delay parameter to call the delay subroutine, and then go drive LED control signal. Different sampling values, the LED flashing frequency. When the potentiometer rotation ST triple development board, you can see the LED flashing frequency change.)
