Listing of Communication in Scripts

In this project, we seek to minimize the gap-to-capacity (given by Shannon's theoretical limit) of a rate 1/3 code (also can be modified for 1/N). This is done via a convolutional encoder/decoder for varying memory elements as well for both soft and hard decoding scheme.

This is a simple program written so the equations look like classical matrix equations and it solves the voltage out of the standard current driven loop filter. This is intended to be used in some future PLL analysis program, but it outlines the way to set up the equations, and solve them.

MATLABs most commonly used 3-d plotting tools surf and mesh require rectangular grids to plot in 3-d, not x,y,z triples. This function converts arrays of x,y,z triples into rectangular grids to use with surf, mesh, etc. common usage: [x y z] = xyzplotter(xin,yin,zin) xin,yin,zin are n x 1 arrays that define your surface.

A given polynomial p(x) is transformed into a rational function r(x). The poles and residues of the derived rational function are found to be equivalent to the roots and multiplicities of the original polynomial. p(x) = Given polynomial = PROD[k=1:K]{(x - z_k)^m_k} d(x) = (d/dx)p(x) g(x) = GCD(p(x),d(x)) u(x) = p(x)/g(x) w(x) = (d/dx)u(x) v(x) = d(x)/g(x) r(x) = v(x)/u(x) = SUM[k=1:K]{m_k/(x - z_k)} Thus, the roots z_k are computed from solving the simple-root polynomial u(x)=0, instead of the original multiple-root polynomial p(x)=0; and the multiplicities m_k are determined as the partial fraction expansion coefficients of the derived rational function r(x)=v(x)/u(x), z_k = Roots(u(x)), k=1,K m_k = v(z_k)/w(z_k), k=1,K In addition, re-constructing a polynomial pz(x) from the computed z_k and m_k, the overall deviation error of the original polynomial p(x) is calculated, er = Norm(pz - p)/Norm(p) The polynomial GCD is calculated from "Monic polynomial subtraction" derived from the longhand polynomial division in classical Euclidean GCD algorithm.
