这个程序是用matlab 编写的GMSK的调制程序希望对大家有用(This program is to use matlab GMSK modulation of the program for people to use)

Implementation of cl_page for LOVSUB layer.

说明：  本程序旨在计算在整个调节时段的初末水位已知的情况下（水位均为170米），从后往前计算出每个阶段的各个水位到最后阶段的最优发电效益，逐步向前递推找出最大年发电效益，从而找到最优化的路径放入到矩阵LJ中，本程序未考虑防洪限制。(The purpose of this procedure is to calculate the optimal power generation benefit for each stage from the rear to the final stage (the water level is 170m) in the case where the initial water level of the whole adjustment period is known (the water level is 170m), and the maximum annual power generation benefit can be found gradually forward. In order to find the optimized path into the matrix lj, the procedure does not take into account the flood control limitation.)

The Interleaved Frequency Division Multiple Ac- cess (IFDMA) scheme is based on compression, repetition and subsequent user dependent frequency shift of a modulated signal. Multiple access is enabled by the assignment of overlapping but mutually orthogonal subcarriers to each user. In this paper it is shown that IFDMA can be regarded as unitary precoded OFDMA with interleaved subcarriers. On the other hand, IFDMA is shown to be a CDMA variant with frequency domain orthogonal signature sequences and chip interleaving. Thus, it combines the advantages of single and multi carrier transmission such as low peak to average power ratio, orthogonality of the signals of different users even for transmission over a time dispersive channel and low complexity. Simulation results show the good performance of coded IFDMA transmission over a mobile radio channel for different data rates.
