Complex matrix algebra is of great importance to a wide variety of applications. One of the most important application areas is telecommunications. Matrix calculations are used in communications ...

For high data rate wireless communications they use Orthogonal Frequency Division Multiplexing (OFDM) due to its high spectral efficiency and low computational complexity. It gives the architecture of ...

In 1948, Alan Turing came up with LU decomposition, a way to factor a matrix and solve \(Ax=b\) with numerical stability. Although there are many different schemes to factor matrices, LU decomposition ...

For Kalman filter processing where matrix inversion is always required the roundoff error can be a problem with small word-length machines. A class of Kalman filter ...

The forums are replete with people trying to learn how to efficiently find inverses of matrices or solve the classic \(Ax=b\) problem. Here's a decent method that is fairly easy to learn and implement ...
