The Empirical Mode Decomposition is a technique to decompose a given signal into a set of elemental signals called Intrinsic Mode Functions. The Empirical Mode Decomposition is the base of the so-called 'Hilbert-Huang Transform' that comprises also a Hilbert Spectral Analysis and an instantaneous frequency computation.

Until recently, Base station antennas have been omnidirectional or sectored. This can be regarded as a waste of power as most of it will be radiated in other directions than toward the user. In addition, the power radiated in other directions will be experienced as interference by other users.

This transformation is non-redundant, approximately shift-invariant and produces oriented filters in 2D and 3D. There is a m-file called 'example.m' which shows how one can use this package. For more information see the following paper: Hosseini, Vafadust : "Almost Perfect Reconstruction Filter Bank for Non-redundant ,Approximately Shift-Invariant, Complex Wavelet Transforms".

This toolbox includes a complete set of blocks implemented in the Simulink environment, which allows designers to perform time-domain behavioral simulations of switched-capacitor sigma-delta modulators. The proposed set of blocks takes into account most of the SC sigma-delta modulator non-idealities, such as sampling jitter, kT/C noise and operational amplifier parameters (white noise, finite dc-gain, finite bandwidth, slew-rate and saturation voltages).
