Modern High Speed Wireless Communications:

H.Zaghloul, “Wireless Infrastructure: OFDM shoulders heavy RF traffic,” EE Times, 27 Feb 2001.

Zaghloul and Fattouche teamed up in 1989 to work on wireless communications. They first worked on characterizing the indoor propagation channel.

By 1991, they invented a model equalizer for fading channels that removes some of the irreducible bit error rate thus increasing the information carrying capacity of a noisy channel.

In 1992, they developed wideband OFDM that improved on conventional OFDM in three ways: it used the simple channel estimator to remove the effects of the propagation channel;

it scrambled the phase of the signal before it entered into the FFT which reduced the peak to average problem of OFDM; they removed classical hardware carrier and clock recovery and replaced them with digital techniques.
These opened the door for the high speed WiFi and WiMAX.

The second improvement was then applied to codes in CDMA and helped in introducing the speed improvements in 3G and LTE.

Characterizing and Modeling the Radio Propagation Channel:

Hatim Zaghloul was the first to use a standard network analyzer to measure the indoor channel. This opened the door for a whole suite of measurements by his team as well as other teams of researchers. The measurements were then used to characterize the channel and helped in the invention of wideband OFDM which is the foundation of WiFi and WiMAX.

Spherical Tokamak Plasma Confinement:

Hatim Zaghloul together with Dr. Kevin Volk, Dr. H. Buckmaster and O. Barajas did work on electromagnetic fields. The first three proved that the electric and magnetic fields could be parallel in an electromagnetic wave contrary to prior conceptions. They derived the general condition for monochromatic plane waves to have E || B. They went on to characterize these waves and find interesting applications for them. Zaghloul and Barajas worked on force-free magnetic fields which are magnetic fields generated by currents that align themselves so that the net magnetic force on them vanishes. They found the solution for the fields in spherical coordinates. Zaghloul then applied this to spherical tokamaks for the confinement of plasma in nuclear reactors.
