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)

Fifth problem, Pattern Simulation of inverse transform
Ⅰ, basic tasks: decision by the sampling pattern after AMI and CMI pattern sequence to recover the original digital PCM pulse code signal.
Main steps and requirements:
(1) post-judgment by the AMI code sample digital sequence to restore the original PCM pulse code signal (signal 0,1). AMI requires post-judgment sampling digital code sequence can also be a numeric character asked to draw a pattern waveform before and after the inverse transform.
(2) post-judgment by the CMI sampling digital code sequence to restore the original PCM pulse code signal. Requirements of post-judgment CMI sampling digital code sequence can also be a numeric character asked to draw a pattern waveform before and after the inverse transform.
Ⅱ, choose to do the task: the post-judgment by the sample type HDB3 code sequence to recover the original digital PCM pulse code signal.
