ifdma_tfrank
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.

boxplot_percentwhisk
Normally boxplot plots the whiskers with a maximum length based on the distance between the 25th and 75th percentile. This script uses boxplot but plots the whiskers for a specified percentile and only plots the outliers beyond the new whiskers.
Note that the percentile is defined as the data point just beyond the calculated percentile. For example, if the 98th percentile lies between the 4th and 5th highest data points, then the 4th highest data point will be considered the 98th percentile, the whisker will extend to the 4th highest, and only the 4 highest values will be plotted as outliers.
