通过matlab编程 进行GPS单点定位进行测速来反映所测地点晃动情况，采样数据1s（1Hz） loadobsrinex.m 为接收机即所用GPS得到的监测数据，loadrinexGpsn.m GPS星历数据，single_v_main1.m是主程序，还有其他消除误差程序。(Through matlab programming for GPS single point positioning speed to reflect the test place moving situation, and the sampling data 1 s (1 hz) Loadobsrinex. M for monitoring data, used the GPS receiver got loadrinexGpsn. M GPS ephemeris data, single_v_main1. M is the main program, and other procedures to eliminate error. )

The demand of high data rate services has been increasing very rapidly and there is no slowdown in sight. We know that the data transmission includes both wired and wireless medium. Often, these services require very reliable data transmission over very harsh environment. Most of these transmission systems experience much degradation such as large attenuation, noise, multipath, interference, time variance, nonlinearities and must meet the finite constraints like power limitation and cost factor. One physical layer technique that has gained a lot of popularities due to its robustness in dealing with these impairments is multi-carrier modulation technique. In multi-carrier modulation, the most commonly used technique is Orthogonal Frequency Division Multiplexing (OFDM)
