CALCULATING CHANNEL CAPACITY FOR MIMO CHANNEL IN DIFFERENT FORM.HERE WE CONSIDERED TWO,THREE AND FOUR INPUT AND OUTPUTS.

Chebfun is an open-source software system for numerical computing with functions. The mathematical basis is piecewise polynomial interpolation implemented with what we call “Chebyshev technology”. The foundations are described, with Chebfun examples, in the book Approximation Theory and Approximation Practice (L. N. Trefethen, SIAM 2013). Chebfun has extensive capabilities for dealing with linear and nonlinear differential and integral operators, and also includes continuous analogues of linear algebra notions like QR and singular value decomposition. The Chebfun2 extension works with functions of two variables defined on a rectangle in the x-y plane.

说明：  OFDM系统的PAPR性能与分割方式有关，但除此之外还与输入数据的子分组数V、相位集合中的相位数P以及子载波数量N有关。下面，对各种条件下PTS-OFDM系统的性能进行了仿真。(PAPR performance of OFDM systems and partitions the way, but in addition to the input data, the number of sub-group V, number of phases in the collection phase P and N on the number of subcarriers. Here, a variety of conditions PTS-OFDM system performance is simulated.)

Denoising Reduces the total-variation of the image. Filters out noise while preserving edges. Textures and fine-scale details are also removed. In this demo the assumption is that a white Gaussian noise is added with a-priori known (or estimated) noise power (variance). The fidelity term to the input image is calculated automatically so that the power of the noise is reduced.
