With a total of 2 patents, Ganem's work has had a considerable impact on communication technologies.

Latest Patents

Ganem's latest patents include a demodulator for constant envelope and continuous phase signals. This demodulator is designed for use with angle modulated signals that convey a sequence of binary symbols. The technology treats the signal as a sequence of elementary pulses that have been amplitude modulated using a principal function derived from the frequency pulse characteristic of the modulation. The demodulator features two filters matched to the principal function, which receive quadrature components of the complex envelope of the received signal. These filters are followed by samplers, and a calculating circuit operates at the bit rate to calculate metric increments based on stored complex samples. This information is then transmitted to a decision circuit that employs a dynamic programming algorithm to determine the values of the bits in the sequence recursively.

Another significant patent is the electronic antenna decoupling process and device. This innovation provides a method for decoupling a receiving antenna located near a transmitting antenna that emits a frequency modulated interfering signal. The process involves superimposing a signal on the static control of variable attenuators, which are part of a regulation loop designed to cancel out the interfering signal received by the antenna. The amplitude of this signal is proportional to the difference between the carrier frequency of the interfering signal and the instantaneous value of its modulation signal.
