CDMA多用户检测的Simulink仿真研究(CDMA multi-user detection of Simulink Simulation)

用SLM方法来减小OFDM系统的PAR，给出在不同的M值下，系统的PAR曲线图。(To reduce the use of SLM OFDM system PAR, gives the different values ​ ​ of M, the system PAR of Fig.)

其中的相应程序为实现解决非线性方程组的相应的方法，程序测试正确。(Corresponding procedures for the realization of the appropriate method to solve unlinear equations, the correct program testing.)

routine to take the Fourier transform of a signal and plot both the time and frequency domain representations

main executing reference usage: usage_timeDifference.m Sample output: The time interval between earierTime [09-Sep-1900 09:09:18] and laterTime [31-Oct-2010 23:33:08] is 110 years, 79 days, 14 hours, 23 mins, 50.17 secs. The objective is to compute the time interval taking into account the leap days that are subsumed within the time interval. Note: The logic subsumes the time interval by yearEnd, monthEnd, dayEnd - timeEarlier (within that year) + time interval (excluding that 2 years) + timeLater - yearEnd, monthEnd, dayEnd (within that year) It differentiates the earlier time and later time, ie. timeDifference (earlierTime, laterTime) gives the same result as timeDifference (laterTime, earlierTime). leapDayHasPassed.m illustrates a possible approach to determine if a certain day of concern is already over at a given time. Caveat: does not include leap secs
