MPSKTransmissonwithGausNoise
本程序用于完成BPSK、QPSK、8PSK的调制仿真。并可任意扩展到MPSK和MQAM。程序分成三个部分：phase.m对基带码元序列进行脉冲成型，可选矩形脉冲，升余弦脉冲和平方根升余弦脉冲； model.m 为主程序，完成各种信号的基带星座图映射、脉冲成型和调制； command.m给出一个简单的频谱显示测试。(This procedure for the completion of BPSK, QPSK, 8PSK modulation simulation. Arbitrary and may be extended to MPSK and MQAM. Program is divided into three parts: phase.m symbol of the baseband shaping pulse sequences, optional rectangular pulse, the square root raised cosine pulse and raised cosine pulse model.m-based procedures, completed a variety of base-band signal constellation mapping , pulse shaping and modulation command.m given spectrum shows a simple test.)

Calculate-Time-Interval
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
