Description: The chebfun project is a collection of algorithms, and a software system in object-oriented Matlab, which extends familiar powerful methods of numerical computation involving numbers to continuous or piecewise-continuous functions. It also implements continuous analogues of linear algebra notions like the QR decomposition and the SVD. The mathematical basis of the system combines tools of Chebyshev expansions, fast Fourier transform, barycentric interpolation, Clenshaw-Curtis quadrature, and recursive zerofinding.

Description: PERFORMANCE ANALYSIS OF OFDM
Orthogonal Frequency-Division Multiplexing (OFDM) — essentially identical to Coded OFDM
(COFDM) — is a digital multi-carrier modulation scheme, which uses a large number of closely-spaced
orthogonal sub-carriers. Each sub-carrier is modulated with a conventional modulation scheme (such as
quadrature amplitude modulation) at a low symbol rate, maintaining data rates similar to conventional
single-carrier modulation schemes in the same bandwidth. In practice, OFDM signals are generated and
detected using the Fast Fourier transform algorithm.
