MAKELATT Create lattice
L = MAKELATT(KIND,PTS,DIM) makes desired kind of dim-dimensional
finite lattice that consists of pts elements. Available designs are
listed in the table below. All the generated lattices are
geometrically uniform. The lattice points are chosen from the origin
to higher shells. Sometimes its usefull to generate lattices from the
number of one dimensional pattern side i.e. PTS = DIM ^ SIDE.
Table of available designs
Design | Dimension | KIND
-----------+-----------+----------
Zn | n>=1 | Z
An | n>=1 | A
Dn | n>=3 | D
Hexagonal | n=2 | Hex
fcc | n=3 | fcc

Linear prediction follows naturally from the general mathematics of linear
systems. As the system output is defined as a linear combination of past samples,
the system’s future output can be predicted if the scaling coefficients bj and ak
are known.

Contrast is the difference in luminance or color that makes an object (or its representation in an image or display) distinguishable. In visual perception of the real world, contrast is determined by the difference in the color and brightness of the object and other objects within the same field of view. Because the human visual system is more sensitive to contrast than absolute luminance, we can perceive the world similarly regardless of the huge changes in illumination over the day or place to place. The maximum contrast of an image is the contrast ratio or dynamic range

papr to differenrt number of subcarrier:
we put N = 256,512,1024 and show the output ofp ccdf with papr when we use QPSK modulation.
The PAPR ratio is a measure of the dynamic range in OFDM signals. Thus high
PAPR induces a high dynamic range which describes high variability in the
signal range.
complex data sequences are input to the IDFT of an OFDM transmitter
then at the output of the IDFT, real and imaginary parts are obtained.
