Multiple-input multiple-output (MIMO) systems require simplified architectures that can maximize design parameters without sacrificing system performance. Such architectures may be used in a transmitter or a receiver. The most recent example with pos

Orthogonal Frequency Division Multiplexing (OFDM) is chosen as a multiplexing technique and broadly used in today’s radiocommunication environments to overcome spectrum insufficiency. In current OFDM applications, the IDFT/DFT algorithms are used f

Model based iterative reconstruction techniques (MOR) in Electrical Tomography have the potential to produce the most physically realistic reconstructed images. However the real-time performance of this method is presently constrained by the high com

This paper presents a new design method for clutter IIR filters that maximize the 3 dB bandwidth of the dynamic frequency response. The designed filters offer better dynamic frequency responses for a given number of samples when compared to zero and

This paper introduces a new method for initializing a digital real second order IIR notch filter at two frequencies. It requires only the first received sample to initialize the filter's internal memories to their steady state values. The new method

IIR filters designed for steady state operation suffer from the transient effect caused by processing a finite number of samples. Their performance, however, can be improved by using initialization techniques. This paper presents a new design method
