The m-sequence with Cyclic Prefix is inserted between OFDM symbols in time domain as training sequence. The cross-correlation is calculated between the received sequence with CP removed and the appointed circular shifted m-sequence, which takes reliability of the estimation of channel impulse response on account of the two-valued auto-correlation property of the m-sequence, thereby the channel frequency response can be advisably decided.

在时域OFDM符号之间插入附加循环前缀的m序列作为训练序列，在接收端将去掉循环前缀的接收序列与指定的循环移位m序列作相关运算，然后利用m序列的二值自相关特性获得信道的冲激响应估计，从而得到信道的频率响应估计。

Comparing the run_time between insertion sort and quicksort shows insertion sort gives better performance when the given data sequence is in ascending order. For the nearly sorted list, whether insertion sort performs better than quicksort depends on the size of the list and the number of randomly ordered items. Compared to the insertion sort, the results show quicksort yields shorter run_time if the list is in descending or random order. The main drawback of quicksort is the worst case behavior of O(n2) comparisons when the list is in ascending or descending order. It has been shown that quicksort also performs poorly for nearly sorted list.

通过插入排序和快速排序执行时间比较显示：当序列以递增次序排列时，插入排序的表现比快速排序好；对于基本有序序列，插入排序算法是否比快速排序算法好取决于序列的大小和基本有序序列中随机分布元素的多少；对于递减和随机序列，快速排序的运行时间比插入排序好。

The major achievement of this paper is: Based on characteristics of the traffic data distribution, execute pattern recognition operations on traffic condition on two dimensions by clustering, then use BP neural network to describe and forecast traffic flow aiming at each pattern. Making use of classic flow-occupancy inverse "V" model, implement polynomial fitting using least-squares algorithm and statistics method on flow curves to detect outliers which are proved to be not accord with practice through the actual implement, then use the moving average model to recorrect the outliers and absent. Make correlation analysis on muti-direction flow queues of the intersection and ones of upriver intersections, choose flow queue with high correlation as assistant one to improve the error tolerance of the prediction system, at the same time we can use the method to give an estimation of flow in intersection with out sensors.
