First, the stations'timing process and the slot aligning are discussed. Second, the dissertation propose a resource request random access method based on feedback. The performances of this method are analyzed. Third, proceed from the considerations of the MAC protocol for the HFC system, a QOS-oriental scheduling algorithm for the MAC protocol based on dynamic TDMA is proposed. Simulation results show that the performance of this algorithm is better than that of the first come first service. Forth, two contention resolution algorithms ----p-persistent CRA and tree CRA, which are usually adopted in the HFC system, are summarized. The delay and characteristic are compared. At last, the dissertation introduces the function implementation of the MAC layer based on COM21 UPSTREAMS.

首先，讨论了基站的同步进程和时隙同步的实现；然后，本文提出了一种带反馈模块的资源申请信号随机接入方法，并对其进行性能分析；然后，从HFC系统的MAC协议出发，提出了一种用于基于动态TDMA技术的MAC协议的业务安排算法，计算机仿真结果表明其性能优于先到先服务法的性能；然后概述了常用于HFC系统的两种冲突解决算法——p-坚持冲突解决算法和树型冲突解决算法，比较两者的时延性能与特征；最后，介绍了基于COM21 UPSTREAMS协议的MAC层功能实现，给出了硬件框图和照片。

A kind of GCL(Generalized chirp-like) sequences are adopted as the preambles of the random access channel, and a cyclic postfix is added. This structure can utilize the perfect periodic correlation properties of GCL sequences effectively to improve the detection performance.

采用具有GCL(General chirp-like)序列作为随机接入信道的前导码，并加上了循环后缀，该结构能够有效利用GCL序列良好的周期相关特性提高检测性能。

The effectiveness of market theory tells us that stock prices fluctuate in line with the random walk model, only the price history of the historical information contained herein, which is the basis for the creation of the technical analysis of the premise - is a repeat of history, the history of the price includes all the information is a huge challenge , And most of the technical analysis of empirical studies have shown that even if technical analysis can be brought about by excess profits, excess profits that are often not considered in the transaction costs of the case emerged, whether technical analysis can provide investors with continued access to Excess profits have doubts about that.

市场有效性理论告诉我们，股票价格波动符合随机漫步模型，历史价格只包含历史信息，这对技术分析赖以成立的前提——历史是不断重复的，历史价格包含所有信息是一种巨大的挑战，而大多数对技术分析实证研究也表明，即使技术分析能够带来超额利润，这种超额利润也通常是在不考虑交易成本的情况下出现的，技术分析能否可以让投资者持续地获取超额利润是有疑问的。
