II By calculating the unit exergy cost of the combined thermal power generation system using matrix model, validating the conclusion that the unit exergy cost of the whole system goes up gradually, and confirming the conclusion about the integration density influence on the systemic calculating results, it can be found that the unit exergy cost of the whole system goes up gradually because exergy loss increases with the exergy used to create exergy flux with the going-on of the process.

由此可以推知系统的集成度越低，子系统划分的越细，计算得到的结果越准确。（3）会计模式和矩阵模式方法在应用时有各自不同的侧重点和适用范围，矩阵模式方法在用于确定系统的划分即集成度的影响时有很大的作用，系统的划分明确对于整个计算至关重要；而会计模式方法在涉及到非能量费用的计算时有比较明确的思路和方法。

to reduce the impact of carrier frequency offset in ofdm system,this thesis designs a new carrier frequency offset estimation scheme for ofdm system.the carrier frequency offset estimation includes acquisition and tracking.we adopt variable step size adaptive algorithm.the acquisition range of the proposed algorithm is as large as one half of the overall signal bandwidth.through this method we can not only avoid the feedback by using forward error correction,but also reduce the times of complex multiplication in order to reduce the power consumption of the system.this algorithm not only has low complexity and fast convergence nut also can improve the demodulation performance of ofdm system.computer simulation illustrates the superior performance of the proposed algorithm with regard to estimation accuracy in both awgn channel and multi—path channel.

摘 要：为了减小正交频分复用系统受频率偏差的影响，在ofdm系统中设计了一种新的载波频偏估计算法。频偏估计包括跟踪和捕获两个阶段，文中采用变步长自适应算法来进行跟踪，这个跟踪算法的捕捉范围是整个信号带宽的一半。通过此方法，不但可以利用前向纠错的方式来避免反馈，而且可以缩减复数乘法的次数以降低计算复杂度和系统功耗。该方法运算复杂度低，并具有较好的收敛性，能改善odfm的解调性能。从计算机的仿真效果可以看出无论是在awgn信道上还是在多径信道上都表现出了卓越的性能。
